核心抗体阳性是什么意思
一般来说，出现核心抗体呈阳性一般是在检测报告里面。
乙肝核心抗体阳性来说的话，说明检测者的身体感染了乙肝病毒。
核心抗体阳性不能单独的去作分析，不然不能确定患者的身体具体情况。
阳性含义
乙肝核心抗体阳性说，已经感染了乙肝病毒，这是一个永远的象征，只要一旦感染了乙肝病毒就会存在。
但在实际检测中，由于不同时期的核心抗体水平在体内是不同的，或在不同的医院检查，仪器和试剂之间的误差，有时为负。
而在医学理论中，核心抗体是抗体的标志物。
乙肝核心抗体阳性要和表面抗原、E抗原在一起分析才有临床意义，单独核心抗体阳性，只能说感染过HBV，但没特别的临床症状。
临床上，大三阳，小三阳，都不一定有症状，主要看肝功能，肝功能有问题才可能会出现临床症状，如黄疸，消化不良等。
乙肝核心抗体阳性有两种意义
一种是乙肝核心抗体阳性，但IgM抗体水平较低，表示以前感染过乙肝病毒，现在已经康复，可以和正常人一样的生活。
另外一种是乙肝核心抗体阳性，IgM抗体的水平也比较高，表明体内有乙肝病毒存在，且乙肝病毒正在复制，有传染性，这种情况需要进行抗病毒治疗。
但是如果单独分析乙肝核心抗体一般不会有太大的意义，要和其它几项在一起分析，如果表面抗原、e抗原和核心抗体同时呈阳性，这表示是有乙肝大三阳;如果表面抗原、e抗体和核心
抗体同时呈阳性，这表示是有乙肝小三阳。
乙肝五项各项指标详解一、乙型肝炎表面抗原(hepatitisBsurfaceantigen,HBsAg)是乙型肝炎病毒(hepatitisBvirus,HBV)外壳蛋白，是乙肝感染后首先出现的病毒标志物，可作为乙型肝炎早期诊断和普查指标。
孕妇、手术前、输血前、有创检查前都要检查血清HBSAg,及时发现HBV感染。
血清HBSAg阳性表示HBV感染，常见于急性肝炎、慢性肝炎或无症状携带者。
急性肝炎恢复后，一般在广4个月内HBSAg消失，持续6个月以上则认为转为慢性肝炎Q无症状HBsAg携带者是肝功能正常的乙肝患者，虽然肝组织已有病变，但无临床症状。
血清HBsAg阴性不能完全排除HBV感染，需要结合乙型肝炎血清学其他指标综合判断。
HBsAg阴性常见于隐匿性HBV感染者，这类患者因HBsAg抗原表位变异，造成HBSAg阴性，但是血液或肝组织中HBVDNA阳性；也见于应用乙肝免疫球蛋白和长期使用抗病毒药物引起HBV突变，导致HBSAg阴性Q 需要注意的是：个别病例胆红素浓度过高可使血清HBSAg结果出现假阳性。
对于接受高剂量生物素(维生素B7)(>5mg∕天)治疗的患者，须在末次生物素治疗8小时后采集样本。
接受肝素治疗的患者，样本可能凝固不全，纤维蛋白存在可能会影响结果，因此应在肝素治疗前采集样本。
二、乙型肝炎表面抗体(hepatitisBsurfaceantibody,HBsAb)是乙型肝炎病毒(hepatitisBvirus,HBV)刺激机体产生的特异性抗体。
HBsAb阳性常见于HBV感染恢复期或接种乙型肝炎疫苗后，其为保护性抗体，阳性表示对HBV有免疫力，但是如伴有高效价HBSAb者，不能排除肝脏有持续性HBV感染的可能。
接种乙肝疫苗后，有抗体应答的保护效果一般至少可持续30年。
HBsAb阴性常见于未曾感染HBV或未接种过乙肝疫苗的人群。
但是HBsAb阴性不能排除HBV感染，HBsAb是HBV感染后最晚出现的特异性抗体Q急性HBV感染6个月后可检测到HBSAb,慢性HBV感染者可能数年都不能检测到HBSAb。
乙肝五项说明：1.乙肝表面抗原：是乙肝病毒的外壳蛋白，本身不具有传染性，但它的出现常伴随乙肝病毒的存在，所以它是已感染乙肝病毒的标志。
在感染乙肝病毒2个月～6个月后，可在血清中测到阳性结果。
它的出现表明是急性乙肝、慢性乙肝患者或病原携带者，急性乙肝患者大部分可在病程早期转阴，慢性乙肝患者或病毒携带者表面抗原可持续阳性。
2.乙肝表面抗体：是对乙肝病毒免疫和保护性抗体。
它的阳性表明既往感染过乙肝病毒，但已经清除乙肝病毒，或者接种过乙肝疫苗，产生了保护性抗体。
血清中乙肝表面抗体滴度越高，保护力越强。
但也有少数人乙肝表面抗体阳性而又感染了乙肝，可能为不同亚型感染或是乙肝病毒发生了变异。
3.乙肝e抗原：急性或慢性乙肝患者体内可查出乙肝e抗原，它的阳性说明乙肝病毒在体内复制活跃，传染性强。
4.乙肝e抗体：它的阳性表明患者的传染性降低，乙肝病毒复制降低或缓解。
也有个别人e抗体阳性，病情迁延不愈，多为感染了变异的乙肝病毒所致。
5.乙肝核心抗体：为曾经感染过或正在感染者都会出现的标志。
核心抗体IGM是新近感染或乙肝病毒复制标志，核心抗体IgG是感染后就会产生的，对于辅助乙肝两对半检查有一定意义。
乙肝五项指标结果怎么看?武汉国中堂肝病研究所专家在这里简单给我们做个介绍：1)第一项乙肝表面抗原(HBsAg)阳性，其余阴性。
说明被乙肝病毒感染了。
很多单项乙肝表面抗原阳性者体内的乙肝病毒已被清除，不再具有传染性。
但是仍有一部分患者体内可以查到乙肝病毒的存在，仍具有传播性，应注意传染，更不能献血。
2)第一项、三项阳性，即乙肝表面抗原(HBsAg)和乙肝e抗原(HBeAg)阳性，其余三项阴性。
表示感染了乙肝病毒，可能处在急性乙肝、慢性乙肝或乙肝携带者活动期，病毒复制活跃，传染性强;一、三、五项阳性就是常说的乙肝大三阳，意义与一、三项阳性差不多。
3)第一、四项阳性，即乙肝表面抗原(HBsAg)和乙肝e抗体(HBeAb或抗HBe)阳性，其他阴性。
乙肝两对半检查结果对照表-25种(16+9)组合的意义乙肝两对半乙肝两对半是目前国内医院最常用的乙肝病毒感染检测血清标志物，两对半检查项目包括：表面抗原、表面抗体、e抗原、e抗体、核心抗体。
因为核心抗原的检测方法较复杂，临床上通常不做，所以在“乙肝五项”检查中，前四项是两对，核心抗体是半对，因此被称为“乙肝两对半”。
概述乙肝两对半是国内医院最常用的乙肝病毒（HBV）感染检测血清标志物。
乙型肝炎病毒免疫学标记一共3对，即表面抗原（HBsAg）和表面抗体（抗HBs或HBsAb）、e抗原（HBeAg）和e抗体（抗HBe或HBeAb）、核心抗原（HBcAg）和核心抗体（抗HBc或HBcAb）。
乙肝两对半又称乙肝五项，其检查意义在于：检查是否感染乙肝及感染的具体情况，区分大三阳、小三阳。
乙肝两对半检查的临床意义乙肝两对半[3]（乙肝五项）是目前国内医院最常用的乙肝病毒（HBV）感染检测血清标志物。
乙肝五项反映乙肝病毒免疫学标记一共3对，即表面抗原（HBsAg）和表面抗体（抗HBs或HBsAb）、e抗原（HBeAg）和e抗体（抗HBe或HBeAb）、核心抗原（HBcAg）和核心抗体（抗HBc或HBcAb），通常核心抗原没有检验，所以通俗的说法就是“两对半”。
乙肝五项检查是用来判断是否感染乙肝或粗略估计病毒复制水平的初步检查，乙肝五项结果只是对乙肝病毒标志物的判断，只能判断体内有没有感染过乙肝病毒或者有没有抗体。
能够分辨受检者是不是乙肝病毒感染者，但并不能确诊是乙肝患者或是乙肝病毒携带者，又或是携带有乙肝病毒的其他疾病，例如乙肝后肝硬化，乙肝伴有肝癌等乙肝两对半是现在国内医院最多见的乙型肝炎病毒（HBV）感染检测血清标志物。
乙肝病毒免疫学标记一共3对，即表面抗原（HBSAg）和表面抗体（抗HBs或HBsAb）、e抗原（HBeAg）和e抗体（抗HBe或HBeAb）、核心抗原（HBcAg）和核心抗体（抗HBc或HBcAb）。
乙肝表面抗原、乙肝表面抗体、乙肝e抗原、乙肝e抗体、乙肝核心抗原及乙肝核心抗体等乙肝两对半指标及结果解读乙肝是乙型肝炎病毒感染导致的肝脏炎症，是威胁我国人群健康最重要的传染病之一，传播途径多样，可通过密切接触、母婴、血液和性传播。
近九成感染者不会出现临床症状，而后，部分感染者可发展为慢性迁延性肝炎或原发性肝癌，对健康危害大。
乙肝实验室诊断，乙肝两对半是必须占有很大一席之地。
实际上HBV 的免疫学标记一共 3 对，分别是 HBsAg（乙肝表面抗原）、HBsAb （乙肝表面抗体）；HBeAg（乙肝 e 抗原）、HBeAb（乙肝e抗体）；HBcAg（乙肝核心抗原）以及 HBcAb（乙肝核心抗体）。
HBcAg 在血清中不易检出，所以只检测剩下的两对抗原抗体和一个单独的乙肝核心抗体，俗称两对半。
乙肝两对半HBsAg（乙肝表面抗原）位于乙肝病毒的表面。
在表面，所以在乙型肝炎患者血清中最先出现，在急性肝炎潜伏期即可出现阳性,是乙肝早期诊断和普查的指标。
HBsAb（乙肝表面抗体)是机体针对乙肝表面抗原产生的抗体，是一种保护性抗体，可以暴揍表面抗原，所以在机体感染或接种乙肝疫苗后会出现。
HBsAg 与 HBsAb 同时阳性可能是不同亚型重复感染或病患正处于血清转换期，即 HBsAg 消失，同时伴 HBsAb 出现。
血清转换期为临床上慢性乙肝治疗的最终目标，对临床个体化治疗有重要的指导意义。
HBeAg（乙肝 e 抗原）乙肝e抗原是 HBV 内衣壳蛋白的分泌型，是一种可溶性抗原，主要存在于乙肝患者的外周血中，为病毒复制及传染性强的标志，一般出现的比 HBsAg 稍晚。
HBeAb（乙肝 e 抗体）是机体针对乙肝 e 抗原产生的抗体，一般出现于 HBeAg 阴转后，阳性表示患者处于急性肝炎恢复期，病毒复制水平低，传染性下降，病变趋于静止。
HBeAg 和 HBeAb 同时阳性可见于 HBeAg 血清学转换，同样对临床个体化治疗有重要意义，是目前临床上慢性乙肝治疗近期目标。
乙肝五项对照表乙肝是一种由乙型肝炎病毒引起的肝炎，严重的乙肝感染可以导致肝硬化和肝癌等严重并发症。
因此，对乙肝进行及时的筛查和监测非常重要。
而乙肝五项对照表是一种常用的检测方法，通过该对照表可以全面评估乙肝患者的病情，帮助医生制定合理的治疗方案。
一、乙肝五项包括：1. 乙型肝炎表面抗原（HBsAg）2. 乙型肝炎表面抗体（HBsAb）3. 乙型肝炎 e 抗原（HBeAg）4. 乙型肝炎 e 抗体（HBeAb）5. 乙型肝炎核心抗体（HBcAb）二、乙肝五项对照表的解读方法：1. HBsAg：阳性表示患者体内存在乙肝病毒，是乙肝的标志性指标。
2. HBsAb：阳性表示患者体内存在抗乙肝表面抗原的抗体，有可能是免疫力对抗病毒的表现，也有可能是接种过乙肝疫苗。
3. HBeAg：阳性表示患者具有高传染性，容易传播给他人，是监测慢性乙肝活动性的指标之一。
4. HBeAb：阳性表示患者体内存在抗乙肝 e 抗原的抗体，通常是治疗后的指标之一。
5. HBcAb：阳性表示患者曾经感染过乙肝病毒，目前是否患病需要结合其他指标来判断。
三、乙肝五项对照表的意义：1. 对乙肝患者进行全面的评估和监测。
2. 指导医生确定治疗方案和随访策略。
3. 评估乙肝患者的传染性和慢性程度。
4. 判断患者的治疗效果和预后情况。
四、需要注意的问题：1. 乙肝五项对照表是乙肝患者日常检测的重要指标，但并非唯一的诊断依据，患者还需要结合临床症状、肝功能检查等综合分析。
2. 对于乙肝患者来说，定期进行乙肝五项检测是非常必要的，可以及时了解自身的病情发展情况，避免疾病恶化。
3. 在进行乙肝五项检测时，患者应该按照医生的要求进行准备，保持身体放松，配合医生完成检查，以确保结果的准确性。
总而言之，乙肝五项对照表对于乙肝患者的诊断、治疗和随访具有重要意义，患者应该重视并认真配合医生进行相关检查。
只有科学合理地进行监测和治疗，才能有效控制疾病的发展，保障患者的健康。
最新的乙肝245阳性解释
乙肝245阳性是指乙肝表面抗体阳性、乙肝e抗体阳性、乙肝核心抗体阳性。
乙肝表面抗体阳性，说明体内有了保护性抗体。
有了对乙肝病毒的免疫力，乙肝e抗体阳性，也提示曾经感染过乙肝病毒，但是现在对乙肝病毒有一定的免疫力，乙肝病毒不再复制。
核心抗体阳性，说明既往感染过乙肝病毒，核心抗体会持续存在很多年，因为乙肝核心抗体的半衰期很长。
3项抗体阳性，说明既往有急性乙型肝炎，和慢性乙型肝炎病史，目前乙型肝炎病毒已经被清除，不具有传染性，乙型肝炎处于康复状态，机体有了免疫力，这种情况下也需要定期检查。
每半年检查乙肝两对半，观察e抗体、核心抗体是否消失，同时需要检查肝功能和乙肝病毒DNA。
观察肝功能和病毒定量，是否还在正常范围，如果还在正常范围，说明乙肝已经治愈。
乙肝表面抗体阳性是什么意思呢?
如果检测的结果表明乙肝表面抗体呈阳性，那么就说明身体是有抵御乙肝病毒的能力，并且乙肝表面抗体的定量越高，其产生的保护力度就会越强。
乙肝表面抗体呈阳性的状态，也不能完全说明患者的身体不会出现病毒性肝炎，所以大家也要做好预防的措施。
★乙肝表面抗体是对乙肝病毒免疫和保护性抗体。
它的阳性表明既往感染过乙肝病毒，但已经排除病毒，或者接种过乙肝疫苗，产生了保护性抗体。
血清中乙肝表面抗体滴度越高，保护力越强。
但也有少数人乙肝表面抗体阳性而又发生了乙肝，可能为不同亚型感染或是乙肝病毒发生了变异。
★★乙肝表面抗体阳性出现意味着在乙肝五项
血清标志物中，抗原是病毒本身的成分，而抗体是机体免疫应答的产物，其临床意义不同。
乙肝表面抗体(抗-HBs)是一种保护性抗体，常在感染恢复后期出现阳性，此时乙肝表面抗原(HBsAg)转阴至少已1个月以上。
抗-HBs于6-12月达高峰，以后逐渐下降，10年内转阴(有时转阴很快)。
★出现时间
★乙肝表面抗体出现的早晚与既往是否感染过乙肝病毒有关。
初次感染乙肝病毒者出现较迟缓，再次感染者出现较早。
多数病例在感染乙肝病毒后4~5个月时出现表面抗体，但滴度不高，持续0.5~3年后逐渐消失。
再次感染者一般于2周内可检出乙肝表面抗体一，且滴度较高。
乙肝表面抗体阳性是啥意思摘要乙肝表面抗体阳性是乙肝病毒感染后产生的一种免疫应答指标，意味着人体已经对乙肝病毒产生了免疫反应。
本文将介绍乙肝病毒、乙肝表面抗体的基本知识，以及乙肝表面抗体阳性的意义、检测方法和临床应用。
1. 乙肝病毒乙肝病毒（Hepatitis B Virus，HBV）是一种DNA病毒，属于乙肝病毒科。
乙肝病毒可以通过血液、性接触和母婴传播等途径传播给他人，是一种常见的传染病。
慢性乙肝病毒感染会导致肝炎、肝硬化、肝癌等严重疾病。
2. 乙肝表面抗体（HBsAb）乙肝表面抗体（Hepatitis B Surface Antibody，简称HBsAb）是针对乙肝病毒表面蛋白（HBsAg）的抗体。
当人体感染乙肝病毒后，免疫系统会产生针对病毒的抗体，其中就包括HBsAb。
HBsAb是乙肝疫苗接种后的一种免疫应答指标，也可以是自然感染后形成的免疫应答指标。
它能中和乙肝病毒，防止病毒侵入肝细胞，从而起到保护肝脏的作用。
3. 乙肝表面抗体阳性的意义乙肝表面抗体阳性意味着人体已经对乙肝病毒产生了免疫反应，通常有以下几种情况：•接种乙肝疫苗后，人体产生了免疫应答，形成了持久性免疫，HBsAb一直呈阳性。
•曾经患有乙肝病毒感染，经过治疗或自身免疫力恢复，病毒已被清除，但免疫系统仍保持着产生HBsAb的能力。
•没有感染乙肝病毒，但接种了乙肝疫苗，产生了乙肝表面抗体。
乙肝表面抗体阳性具有以下意义：•对个体而言，乙肝表面抗体阳性表示对乙肝病毒获得了免疫保护，一般不会发生乙肝病毒再次感染。
•对社会而言，乙肝表面抗体阳性个体在捐献血液、器官等方面的风险较低，对乙肝病毒的传播具有阻断作用。
4. 乙肝表面抗体的检测方法目前常见的乙肝表面抗体检测方法有以下几种：4.1 酶联免疫吸附试验（ELISA）酶联免疫吸附试验是一种常用的HBsAb检测方法。
该方法利用特异性抗原与抗体反应形成复合物，然后通过酶-底物反应，使底物变色，通过测量颜色的强度来判断样品中抗体的含量。
乙肝表面抗体阳性是什么意思乙肝表面抗体阳性和阴性有什么区别乙肝在我们国家，属于一种比较常见的疾病，而根据世卫组织的报道，在全球也已经有将近二十亿人患上了乙肝，因此，当我们在体检的时候，出现乙肝问题之后，往往都特别担心，那么今天我们就一起来了解一下乙肝表面抗体阳性是什么意思。
乙肝表面抗体阳性是什么意思1.乙肝表面抗体阳性指的就是当乙肝病毒进入体内之后，人体的免疫系统受到刺激，此时分泌出来的一种特异的免疫球蛋白G，就是乙肝的表面抗体，这种抗体在人体和其他免疫功能的作用下，能够除掉病毒，保护身体的健康，如果你有乙肝表面抗体阳性，就表示有了表面抗体，证明人已产生了免疫力。
2.而另一种情况是接种乙肝疫苗之后产生了抗体。
接种乙肝疫苗之后，机体也会产生乙肝表面抗体阳性，这同样标志机体已具有了抵抗乙肝病毒的能力，受到乙肝病毒侵袭时，机体不会被传染上乙肝。
人自然感染后或注射乙肝疫苗后，均可产生乙型肝炎表面抗体；但不是所有的人都能产生表面抗体。
乙肝表面抗体阳性和阴性有什么区别1.乙肝表面抗体阴性说明此人没有感染过乙肝病毒，身体也没有对乙肝病毒产生抗体。
其次，可以说是没有注射过乙肝疫苗，或者注射了乙肝疫苗但是没有刺激机体产生抗体。
值得一提的是，检查结果呈阴性的人身体内目前还没有抗体，不足以抵抗乙肝病毒的入侵，是有感染乙肝病毒的可能的。
建议检查结果呈阴性，没有抗体的人及时到医院注射乙肝疫苗，产生对病毒的抗体，从而增强免疫力。
2.乙肝表面抗体阳性表明此人已经感染过乙肝病毒或者使用过乙肝疫苗后刺激体内的免疫系统产生了抗体，身体已经具备了免疫乙肝病毒的能力。
但是，乙肝疫苗并不是一劳永逸的一种疫苗。
随着注射疫苗是时间越长，疫苗的作用也会逐渐减弱，所以需要每隔一段时间就注射一次乙肝疫苗。
当检查结果显示乙肝表面抗体呈为阴性时，疫苗就完全失去了功效，这时就需要再次注射乙肝疫苗使人体产生抗体。
通过上面的描述，我们可以知道乙肝表面抗体阳性，是一种具有保护性的抗体，它可以保护我们的机体不被乙肝病毒进行攻击。
乙型肝炎的诊断标准
乙型肝炎是一种由乙型肝炎病毒（HBV）引起的慢性疾病，其诊断主要依据实验室检查和临床体征。
以下是乙型肝炎的诊断标准：
1.乙肝表面抗原（HBsAg）阳性：HBsAg是HBV的外壳蛋白，其阳性是HBV感染的标志。
当血液中HBsAg阳性时，通常表示存在HBV 感染。
2.乙肝表面抗体（HBsAb）阴性：HBsAb是一种保护性抗体，其阴性表示尚未产生免疫力或免疫力已消失。
3.乙肝e抗原（HBeAg）阴性：HBeAg是HBV核心抗原的可溶性成分，其阴性表示病毒复制可能处于静止状态或复制水平较低。
4.乙肝e抗体（HBeAb）阳性：HBeAb是HBeAg的抗体，其阳性表明病毒复制减少或停止，传染性降低。
5.乙肝核心抗体（HBcAb）阳性：HBcAb是针对HBV核心抗原的抗体，其阳性表示曾经感染过HBV或正在感染中。
在诊断乙型肝炎时，医生还会考虑其他因素，如临床症状、肝功能检查、肝脏超声等。
如果满足上述标准中的至少一条，就可以诊断为乙型肝炎。
同时，医生会根据病情的严重程度和患者的具体情况制定相应的治疗方案。
乙肝核心抗体阳性是怎么回事乙肝核心抗体（HBcAb）阳性是指体内存在乙肝病毒核心抗体。
乙肝病毒核心抗体是一种免疫球蛋白，是体内对乙肝病毒感染产生的一种抗体。
当乙肝病毒感染人体后，人体免疫系统会产生不同种类的抗体，其中包括表面抗原（HBsAg）、表面抗体（HBsAb）和核心抗体（HBcAb）。
其中，HBsAg、HBsAb和HBcAb是检测乙肝病毒感染的重要指标。
在HBsAg阳性的情况下，如果同时检测到HBcAb阳性，表明乙肝病毒已经进入体内，但是免疫系统已经形成了对该病毒的防御，并慢慢把该病毒消灭掉了。
治疗方法：1. 监测：对HBcAb阳性的人，需要每6个月至1年进行一次检测。
这可以保证及时发现和治疗可能的疾病并对症治疗。
2. 病毒抑制治疗：如果检测到HBcAb阳性并伴有HBV DNA阳性，则需要及时进行抗病毒治疗。
抗病毒治疗的目的是抑制乙肝病毒在体内的生长和繁殖，减轻病毒的致病性和减少肝脏损伤，乙肝病毒抑制的同时，应注意保护肝功能。
3. 其他治疗方法：可以使用传统中医治疗、理疗等方法辅助治疗。
中草药如黄芪、灵芝等具有抗炎、保肝、养肝等作用。
理疗包括针灸、推拿等方法可改善肝功能。
注意事项：1.饮食：HBcAb阳性的人饮食应健康、清淡，忌饮酒和吸烟。
多吃水果、蔬菜、鱼类等富含微量元素的食品，它们能够有效减轻肝脏的负担。
2.生活规律：HBcAb阳性的人需要定时作息，保持充足的睡眠时间，并尽可能的减轻身体的疲劳。
这样能改善身体机能，提高身体抵抗力。
3. 接种乙肝疫苗：HBcAb阳性的人应接种乙肝疫苗，以预防相关并发症的发生，同时增加对于病毒的免疫力。
4. 避免高危行为：HBcAb阳性的人尤其要注意避免性行为和血液接触等高危行为，以预防更多的感染发生。
总之，对于HBcAb阳性的人，应该重视该疾病的检测和治疗，同时也应注意日常生活和饮食等方面的规律，关注并接受医生的专业建议和治疗方案，以便更好的控制疾病的发展。
乙肝核心抗体阳性是什么意思乙肝核心抗体阳性是什么意思乙肝两对半中核心抗体阳性，说明曾感染过乙肝病毒，目前处于恢复状态，可以考虑已经自然痊愈。
我国有一亿多乙肝病毒感染者,几乎每天可以接触乙肝病毒感染者，你在社会交流中可能被感染。
乙肝“核心抗体”阳性就像伤口好了留下一个伤疤一样，应该属于健康者，但在临床工作中发现，有极少数人数年后多次复查HBV DNA，时有呈弱阳性，要考虑体内仍存在乙肝病毒的可能，俗称隐匿性乙肝病毒感染。
由于体内有较稳定的T细胞免疫，隐匿性乙肝病毒感染者乙肝病毒复制能力较低，通常HBV DNA检查一般＜103 拷贝/ 毫升，HBVDNA大多200--300拷贝/ 毫升左右，肝组织多无炎症活动，肝功能也大多正常，因而发生肝硬化和肝癌的机会罕见。
但应该重视的是如需要使用免疫抑制剂和化疗者，HBV DNA可能复制活跃，应在使用该类药前先应用抗乙肝病毒药。
也有没有使用免疫抑制剂和化疗者，HBVDNA200--300 拷贝/ 毫升左右，肝功能异常，这种情况需要抗病毒治疗。
并使用敏感方法检查HBVDNA。
乙肝核心抗体弱阳性怎么办乙肝核心抗体是曾经或者现症感染乙肝病毒的标志，乙肝核心抗体弱阳性，也就是乙肝两对半检查中第五项指标弱阳性，乙肝核心抗体弱阳性可能出现在以下三种情况下：1、乙肝核心抗体弱阳性说明以前感染过乙肝病毒，目前已经康复，但没有产生保护性抗体乙肝表面抗体。
或者乙肝表面抗体已经消失，但乙肝核心抗体依然存在。
这是因为乙肝核心抗体比乙肝表面抗体的存在时间要长很多，有些人感染乙肝病毒康复后，乙肝核心抗体可终身阳性或者弱阳性。
此时乙肝核心抗体弱阳性只是说明曾经感染过乙肝病毒。
2、乙肝核心抗体弱阳性也可能是隐性乙肝病毒感染后的一种表现。
3、乙肝患者经过治疗，其他各项指标已经转阴，只剩下少量乙肝核心抗体。
那么，乙肝核心抗体弱阳性怎么办？肝病专家指出，乙肝核心抗体弱阳性的患者可以检查肝功能、HBVDNA，了解肝功能是否正常，体内是否有病毒存在。
乙肝核心抗体阳性是什么意思？
文章导读
医学术语大家都很陌生，不知道啥意思，往往需要医生的结实才能理解，特别是什么阳性，什么阴性，它们又有着什么样的区别，下面我就为大家介绍一下乙肝核心抗体阳性，要了解乙肝核心抗体是什么，下面一起来看看吧。
乙肝核心抗体也叫抗-HBc，英文缩写是HBcAb。
包括乙肝核心抗体IgM和乙肝核心抗体IgG，常用竞争法检测。
HBV感染后，在多数人血清中能检出此抗体，是一种敏感的血清学标志，也是乙型肝炎急性感染的早期标志，在血清中存在的时间很长，有些人滴度很高。
在HBsAg和抗-HBs阴性时，能从血清中检出乙肝核心抗体，高滴度的乙肝核心抗体也是一种传染标志。
在HBsAg和抗-HBs阴性时，能从血清中检出乙肝核心抗体，高滴度的乙肝核心抗体也是一种传染标志
抗体的分类
抗—HBc可分为三型，分别是抗—HBcIgM、抗—HBcIgA、抗—HBcIgG，在HBV感染中这几个型依次出现，也会依次消失，只有IgG这一型可长期存在。
在化验室报告的化验单中，如果只标明“抗—HBc”，没有分型，那么它应当是这三型的总和，不过大部分医院化验室报告的都分为IgM和IgG二型。
乙肝表面抗体阳性、核心抗体阳性（Hepatitis B surface antibody is positive, core antibody is positive）Hepatitis B surface antibody positive, hepatitis B core antibody positiveHepatitis B surface antibody is a protective antibody of human body, which can protect the body from HBV infection. Hepatitis B core antibody positive is infection or previous infection marker. These two simultaneous positive, indicating that the body was originally infected with hepatitis B, is in recovery or has recovered.Is hepatitis B antibody positive to be vaccinated?Whether to need to fight hepatitis B vaccine has the following two kinds of circumstances:1, if you are through hepatitis B vaccine to obtain hepatitis B antibody, it is recommended that every three years you strengthen the injection of a hepatitis B vaccine. Since the production of antibody by hepatitis B vaccine, the antibody level decreases with time. Most of our scholars suggest that it is better to strengthen the injection once three years after immunization. No matter how long apart, as long as the surface antibody titer in 10 international units more than /ml, indicating that the body has immunity to hepatitis B virus (variation hepatitis B invalid). Conversely, if the hepatitis B surface antibody titer is below this value, the injection should be enhanced.2, if the hepatitis B surface antibody is not obtained by injection of hepatitis B vaccine, but because of infection with hepatitis B virus obtained, at this time do not need to inject hepatitis B vaccine. The hepatitis B immune antibody obtained by hepatitis B infection has a relatively long duration.Hepatitis B surface antibody is positive, can be effective against hepatitis B virus invasion, thereby protecting the body from hepatitis B virus infection. The previous generation is generally believed that the injection of hepatitis B vaccine antibody 3-5 and sustainable, if often contact with hepatitis B patients if antibody offset faster, in recent years, clinical evidence of hepatitis B vaccine, hepatitis B surface antibody positive stimulation of antibody titer reached more than 10, most can play a protective role in 8-10, and often with hepatitis B patients contact person although antibody offset faster, but because the trace of hepatitis B virus stimulation, the body may also produce antibodies. If the hepatitis B surface antibody positive, generally do not have to worry about the daily life of infection, suggest that 3-5 check, in order to observe the existence and degree of antibodies, and antibody in weak timely to ensure the continuation of hepatitis B vaccine, antibody titer, and effective against hepatitis B virus, better maintenance of human health.Hepatitis B surface antibody appears weak positive, may have been infected with hepatitis B virus, has been restored to health. Or inoculation of hepatitis B vaccine may also lead to this phenomenon, indicating resistance already. The hepatitis B surface antibody is weak positive, generally is not contagious, but the hepatitis B antibody titer will graduallydecline along with the time, so generally strengthens injection once every 4-5 years. It's better to check two, half a titer below 10 micrograms, and every liter should be strengthened.The commonly used method of injecting hepatitis B vaccine is "0, 1 and June injection", that is, the second needle is injected 1 months after the first injection, and the third needle is injected 6 months after the first needle. According to the hepatitis B vaccine specific instructions, each subcutaneous injection of 5 - 10 micrograms. Seventh months, hepatitis B should be tested five items, the effect of vaccination. If the hepatitis B surface antibody is positive, that is effective, or else to play. Hepatitis B surface antibody is a protective antibody that can protect the body against hepatitis B virus, and its presence is the most important indicator of the effectiveness of hepatitis B vaccine injection.(1) if the hepatitis B surface antibody positive antibody titer is >10, showed that the protective antibody is enough, can to some extent in the prevention of hepatitis B virus attacks, without injection of hepatitis B vaccine to strengthen the needle, after check regularly.(2) if the surface antibody of hepatitis B is weak positive, that is, the titer of antibody is 4-10, then a hepatitis B vaccine should be inoculated to strengthen the needle.Hepatitis B surface antibody quantitative detection of normal value is less than 10 10mIU/m1, significantly negative, the body is not enough to resist the invasion of hepatitis B virus,hepatitis B is susceptible to the crowd, this time the need to fight hepatitis B vaccine booster, thereby enhancing the anti HBV effect; if more than 10mIU/m1, can effectively resist the infection of hepatitis B, and numerical better.Hepatitis B surface antibody (HBsAb) reached its peak in 6-12 months and gradually declined thereafter,Turn negative in 10 years (sometimes very fast).= = =Two half of hepatitis B is the most commonly used hepatitis B virus (HBV) infection detection serum marker in domestic hospitals. There are a total of 3 pairs of hepatitis B virus immunological markers, namely surface antigen (HBsAg) and surface antibody (anti HBs or HBsAb), e antigen (HBeAg) and e antibody (anti HBe or HBeAb), core antigen (HBcAg) and core antibody (anti HBc or HBcAb). Hepatitis B two half, also known as hepatitis B five, and its significance is: check whether the hepatitis B infection and the specific circumstances of infection, distinguish big Sanyang, small sanyang.Because core antigen is not easy to be measured in blood, at present the reagent box does not pass, so there are two half of antigen antibody, this is what people often say "hepatitis B two half and half" inspection, or called "hepatitis B five" inspection.Before the "two half and half", and later added a HBcAb-Igm (core antibody Igm), became the three, and now there is a Pre-S1(hepatitis B virus S1 antigen, S1 antigen), "two half and half" into the "three half and half".Hepatitis B two half of each index significance1 (HBsAg- hepatitis B surface antigen) as a sign of the virus has been infected, does not reflect whether the virus replication, replication, infectious intensity2 (HBsAb- hepatitis B surface antibody) is the hallmark of neutralizing antibodies, whether or not a major marker of recovery or resistance. Hepatitis B vaccination, if only the positive, should be regarded as a normal phenomenon after hepatitis B vaccination; hepatitis B virus infection on their own after the elimination of hepatitis B virus immunity will also have the body of hepatitis B surface antibody, this is a good phenomenon3 (HBeAg- hepatitis B virus e antigen) is a marker of viral replication. Continued positive for more than 3 months have affinity4 (HBeAb- hepatitis B virus e antibody) is a stop sign for viral replication. Viral replication decreases and infectivity is weaker than the HBV virus pattern, but not entirely without infection5 (HBcAb- core antibody) is a sign of a person who has been infected or is infected. The core antibody, IGM, is a marker of recent infection or viral replication. The core antibody IgG is produced after infection and has some relevance forassisting the two half of the test.Surface antigen: indicated that the hepatitis B virus (HBV) has been infected, because the surface antigen is the hepatitis B virus's shell, only this positive is not infectious. 70% - 90% surface antigen positive long-term, such as no symptoms, and liver function is normal, no symptoms of hepatitis B surface antigen carriers, without treatment, do not interfere with the work and study, the antigen positive in the population of China accounts for about 10%.Surface antibody: This is a protective antibody that neutralizes the hepatitis B virus. Clew: it is a kind of good phenomenon to obtain immunity after inoculation hepatitis B vaccine; second, hepatitis B recovery period or once suffered from hepatitis B already more, expressed already had immunity.E antigen: hepatitis B virus replication (reproduction) active, infectious stronger, and its close contact, the possibility of infection is greater. This antigen, such as persistent, suggests chronic hepatitis B virus carriers.E antibody: the condition that expresses hepatitis B patient is relieved, stability or incline to rehabilitation, prognosis is good, infectivity decreases, but do not assure the hepatitis B virus has disappeared completely.This is not the core antibody antibody neutralizing antibody, can not clear the virus, and once was in the body to exist for a long time, he recovered sustainable positive, the positive only recently infected with hepatitis B virus or viruscontinues to replicate (reproduction), or had hepatitis B virus infection, and can not distinguish between past or current infection is sick.9 common patterns1 - the past and present have not been infected with HBV.2 + - (1) previous infection failed to detect resistance to -HBs;(2) recovery stage HBsAg disappeared and anti -HBs did not appear; (3) asymptomatic HBsAg carriers.3 - - + + (1) had previously been infected with HBV; (2) acute HBV infection recovered; (3) a few specimens were still infectious. HBV infection has passed; the window period before the emergence of anti HBs. HBeAg appeared later in the latent period of hepatitis B, but disappeared later than the appearance of HBsAg,Closely related to HBV-DNA. Its clinical significance is as follows: (1) it can be used as an auxiliary diagnosis and prognostic indicator of acute hepatitis B. The recovery of acute hepatitis B usually disappears with the disappearance of HBsAg. If 3-4 months after the onset of acute hepatitis B, HBeAg is positive from Yang, anti -HBE appears, which means the prognosis is good. Onset of 3-6 months, still HBeAg (+), may be the earliest evidence of acute hepatitis becoming chronic.(2) it can help to determine the infectivity of hepatitis B patients or HBV carriers. HBeAg exists in the serum of HBsAg positive patients, indicating that there are Dane granules in the blood, most of which are HBV-DNA positive, and the threeare basically parallel. Therefore, HBeAg (+) is highly infectious. Anti -HBe (+) is generally less contagious. However, if serum HBV-DNA (+) may exist in the HBV variant, there is still a certain infectivity; (3) HBeAg positive suggests HBV replication in vivo. HBeAg appears to be resistant to -HBe before and after disappearance, and this phase is called seroconversion, from the HBV replication phase to the non replicative phase. Resistance to -HBe often indicates a decrease or termination of HBV proliferation. But if the nucleotide sequences of C before the change of HBV gene prevents the formation of HBeAg, HBV still exist in the blood circulation, liver disease may continue to develop, and gradually evolved into cirrhosis; (4) in primary hepatocellular carcinoma, the positive rate of HBeAg decreased, and the anti -HBe, a-FP in HBsAg (+ increased. The patients with liver cirrhosis), anti -HBe (+), a-FP increased, suggesting that early hepatocellular carcinoma; (5) maternal transmission in pregnant women during childbirth (HBeAg +) may spread between the rate of mother to child.4 - + - - (1) immunization with hepatitis B vaccine; (2) previous infection; false positive.5 + + + + acute HBV sensation rehabilitation.6 + + - (1) acute HBV infection; (2) chronic HBsAg carriers;(3) infectious weakness.7 - + - + infected with hepatitis B virus in the past, the virus has been basically cleared, the body in rehabilitation. However, there are still some patients with abnormal liver function andDNA positive. Whether or not there is a variation of the virus, it is still necessary to continue the treatment and still be immune. HBV infection, recovery stage.8 + - + + (1) acute HBV infection tended to recover; (2) chronic HBsAg carriers; (3) infectious weakness. Commonly known as "little Sanyang"".9 + + + - acute or chronic hepatitis B infection. Suggest HBV replication, infection is strong. Commonly known as "big Sanyang"".16 rare patterns10 + - - (1) acute HBV infection early, acute HBV infection incubation period; (2) chronic HBV carriers, infectious weak.11 + + - - (1) chronic HBsAg carriers tend to be negative; (2) acute HBV infection tends to recover.12 + + - - (1) acute HBV infection early, (2) chronic carriers, infectious strong.13 + - + + + (1) acute HBV infection tended to recover; (2) chronic carriers.14 + + - - (1) subclinical HBV infection early; (2) different subtypes of HBV two infection.15 + + - + (1) subclinical HBV infection early; (2) different subtypes of HBV two infection.16 + + + - subclinical or atypical infection.17 + + + + subclinical or atypical infection.18 + + + + - subclinical or atypical infection early. HBsAg immune complexes are newly infected with different subtypes.19 - - + - (1) atypical acute infection; (2) in the early stage of infection before the emergence of anti -HBc, HBsAg titer was low and negative, or false positive.20 + + + atypical acute infection.21 + + + acute HBV infection metaphase.22 - + - + - HBV infection has been restored.23 + + - atypical or subclinical HBV infection.24 + + + - atypical or subclinical HBV infection.25 - + - acute HBV infection tends to recover.7 rare patterns26 + + + + + + a subtype of HBsAg and profiled anti HBs (common); II. Serum converting from HBsAg to anti HBs (Shao Jian).27 - + + + -28 - + + + +29 - + + -30 + - + + -31 + + + -32 + + + + -3 normal modesThe following hepatitis B two half and half result index combination form, all indicated that now is the healthy person, has not infected the hepatitis B virus1. - + - +2. - + -3. - -1, hepatitis B symptoms are often manifested as loss of appetite, nausea, nausea and oil, abdominal discomfort, abdominal distension and so on.2, weak, tired, tired, listless, insomnia and dreaminess.3, jaundice is a more prominent symptom of hepatitis B symptoms, often manifested in urine color becomes dark, eyes, skin yellow.4, hepatitis B patients also often appear in right upper abdomen and right hypochondrium discomfort, pain and other symptoms.Hepatitis B two half of 135 positive, that is commonly known as the "hepatitis B big Sanyang", generally means that hepatitis B virus replication in vivo is more active, relatively strong infection. But the two semi hepatitis B 135 positive and can not explain the severity and the degree of liver damage in hepatitis B patients, to check liver function, liver B and hepatitis B virus load DNA related examination, comprehensive analysis and judgment can generally understand the severity of the replication of hepatitis B virus, and infectious size, and to determine the appropriate treatment according to the situation, to achieve the targeted drug, standardized treatment.Hepatitis B two pairs of semi positive 135, check if the liver function is normal, no other clinical symptoms, ultrasound examination showed no obvious damage to the liver, dynamic observations suggest that a HBV serological and biochemical indicators of liver function and ultrasound examination every 3-6 months.Hepatitis B two pairs of semi positive 135, check if the abnormal liver function, normal transaminase exceed more than 2 times, HBV-DNA positive, is suggestive of chronic active hepatitis, the immune has started, you should grasp the timing of treatment, the need for antiviral and protective therapy under the guidance of professional doctors.Hepatitis B two half of 145, positive refers to in the blood test, hepatitis B surface antigen, e antibody and core antibody is positive, we call it hepatitis B small sanyang.Where appear hepatitis B, two half of 145 positive (hepatitis B, small three yang), all indicate acute or chronic hepatitis B, in vivo viral replication, for hepatitis B virus replication.Hepatitis B two, half of 145 positive, should be further examination of liver function, blood routine, alpha fetoprotein and B ultrasound, so that they and doctors to understand the changes in the condition. Hepatitis B two half of 145 positive (hepatitis B small Sanyang) examination, HBV, DNA is still positive, indicating that hepatitis B virus still exists, is still infectious. Every transaminase is high, virus activity is small, 3 worlds need treatment. Otherwise, the liver will develop toward fibrosis - cirrhosis - liver cancer.In addition, hepatitis B two, half a 145 positive, HBV-DNA negative, normal liver function, many people believe that no treatment. However, liver biopsy showed that 90% of the patients had chronic liver inflammation and had a tendency to liver fibrosis. Some patients even had early cirrhosis and the most serious was cancer. This part of hepatitis B, small Sanyang patients should consider anti fibrosis treatment.Hepatitis B two pairs of semi positive 15 also known as hepatitis B 2 Yang, indicating that patients with infectious is relatively weak, if patients with acute or chronic hepatitis, the patients are contagious: if it is changed from hepatitisand viral replication, suggesting that tends to stop infectious. As long as the regular review of liver function and hepatitis B two half and half, as long as the function of the liver is normal, patients do not have to worry too much.Hepatitis B five, first HBsAg positive, indicating that the presence of hepatitis B virus in the body, is now being infected; hepatitis B five, fifth HBcAb positive, indicating that hepatitis B virus had been infected.To determine the severity of hepatitis B, we should make a more accurate judgement in addition to the five items of hepatitis B (two and a half), combined with liver function tests, hepatic fibrosis indexes and B ultrasonography, and CT findings. 15 hepatitis B positive, suggest further liver function and HBV-DNA examination. Take corresponding measures according to the inspection results.Hepatitis B two half to 245 positive refers to hepatitis B surface antibody, E antibody and core antibody is positive. Hepatitis B surface antibody is an antibody produced by hepatitis B surface antigen to stimulate the immune system,Can protect the body from hepatitis B virus attacks again.About hepatitis B two, half a 245 positive whether contagious, according to liver function, HBV-DNA, liver B ultrasound examination, to determine whether there is no virus replication. If two of 245 patients with positive hepatitis B, liver function is normal, DNA negative without virus replication, neither infectious hepatitis B virus; hepatitis B can exist in two veryfew 245 Yang, but positive for HBV-DNA virus replication, then there may be infected with hepatitis B virus.General hepatitis B two pairs of semi positive 245 January, when second after antibody after hepatitis B e antibody anti -HBe e antibody of hepatitis B will disappear; if the long time does not disappear, there may be a mutation of hepatitis B virus, need to do the relevant checks, timely treatment.Hepatitis B two half of the different combinations of its significance is not the same, the most common patterns are:1. hepatitis B five, 1 Yang, the remaining Yin: shows that the incubation period of acute viral infection is late; HBsAg virus carriers.2. hepatitis B five, 2 Yang, the remaining Yin: once vaccinated hepatitis B vaccine, and immune; second, have been infected with hepatitis B virus, but there have been immune antibodies; may appear false positive.3., hepatitis B five, 5 Yang, the remaining Yin: previously infected with hepatitis B virus, is now in convalescence.4. hepatitis B five, 15 Yang, the remaining Yin: commonly known as the "small two Yang" acute HBV infection; II. Chronic HBsAg carriers.5. hepatitis B five, 25 Yang, the remaining Yin: shows that previously infected with hepatitis B virus, has now recovered and has immunity.6. hepatitis B five, 45 Yang, the remaining Yin: (1) the past infection HBV; II acute HBV infection recovery period, the presence of hepatitis B surface antibody before the window period.7., hepatitis B five, 135 Yang, the remaining Yin: commonly known as the "big three yang" acute or chronic hepatitis B infection; II. Viruses in activity and replication period.8., hepatitis B five, 245 Yang, the remaining Yin: acute HBV feeling, rehabilitation period, has a certain immunity.9. hepatitis B five, 13 Yang, the remaining Yin: commonly known as "big second Yang" acute HBV infection; II chronic HBsAg carriers.10. hepatitis B five, 145 Yang, the remaining Yin: commonly known as "small Sanyang", suggesting acute or chronic hepatitis B, viral replication in vivo, hepatitis B virus replication statusHepatitis B two half and half liver function testDistinguish one: check different indicators(1) the target of the project is hepatitis B five, that is: surface antigen (HBsAg) and surface antibody (anti HBs or HBsAb), e antigen (HBeAg) and e antibody (anti HBe or HBeAb), core antibody (anti HBc or HBcAb).(2) liver function index: routine examination for alanine aminotransferase (ALT), alanine aminotransferase (AST), Gu Cao Gu Cao (AST/ALT), the valley of glutamyl transferase (GGP), alkaline phosphatase (ALP), total bilirubin (TBILI), direct bilirubin (DBILI), indirect bilirubin (IBILI), the total protein (TP), albumin (ALB) and globulin (GLB), than the white ball (ALB/GLB), glucose (GLU), urea nitrogen (BUN), creatinine (CRE), lactate dehydrogenase (LDH-L), creatine kinase (CK), total cholesterol (CHOL), triglyceride (TRIG), uric acid (UA).Difference two: the clinical significance is different(1) the second half of hepatitis B two check significance is: check whether the infection of hepatitis B and the specific circumstances of infection, distinguish big Sanyang, small sanyang.(2) liver function is to reflect the physiological function of the liver, liver function test is to detect whether the liver has disease, the extent of liver damage, as well as to identify the causes of liver disease, to judge the prognosis and to identify the cause of jaundice. Liver function tests are especially sensitive and important to the diagnosis of liver diseases such as hepatitis and cirrhosis.Many patients with hepatitis B will encounter such a situation, check the two semi hepatitis B, the doctor to check the hepatitis B virus DNA, HBVDNA is the hepatitis B virus can replicate the genetic material of the new virus, hepatitis B virus gene. Hepatitis B virus only antigen, and no HBVDNA, it will not infect others, because it does not replicate theability of the virus, the patient will be completely cured. The doctor is measuring the condition of the hepatitis B patient,Need measurement of the blood is contained in the HBVDNA (i.e. qualitative, positive or negative), to determine whether there are infectious; but also the check number with the virus (viral load), is to determine the level of infection, usually in the copy number per milliliter containing the number of virus (copy / ml) with the blood of patients with virus load.Two half of hepatitis B can only reflect the carrying pattern of antigen and antibody in the body and the immunity of the organism under certain conditions, so as to provide indirect evidence for the hepatitis B virus infection. The presence of HBVDNA is the direct evidence of hepatitis B virus infection, and is the gold standard for diagnosis.Hepatitis B two, half a check, and metabolism is not directly related, eating does not affect the HBV antigen antibody indicators, that does not affect the accuracy of the results of the examination. So you don't need an empty stomach.Hepatitis B two half and half examination, do not need fasting examination, but hepatitis B two half and half, often with liver function or hepatitis B ultrasound examination together, to determine the hepatitis B situation. The liver function and hepatitis B ultrasound examination must be fasting, while checking the day before eating light, check the first three days can not drink, in order to ensure the accuracy of inspection. So, if want to check hepatitis B at the same time two half, liver function (hepatitis B, b) must be empty stomach.1, for healthy people, through the injection of hepatitis B vaccine can produce sufficient hepatitis B antibody, 3-5 years to check once five hepatitis B can be, but there are chronic liver disease symptoms, but also need to check the hepatitis B five.2, for regular contact with hepatitis B patients, it is best to go every year to check the hepatitis B antibody titer, once the titer is less than 10, should be timely vaccination hepatitis B vaccine, strengthen the needle.3, for hepatitis B patients, hepatitis B five checks interval depends on their own circumstances, neither between the interval is too long, but too frequent inspection is meaningless. If patients are not treated with special antiviral therapy, there is no need to examine HBV markers and viral variants frequently, and each patient's condition must be selected for an examination to be performed. Under normal circumstances, it is recommended that every three months or six months of the patient's friends to check the hepatitis B five checks. There are five clinical hepatitis B is often carried out with the liver function, especially the hepatitis B patients who have manifested the symptoms of hepatitis B, if the feeling is a little unusual, go to the hospital for examination.Big 3 this world is infectivity, small, 3 this world infectivity is lower, healthy carrier is not infectivity.HBsAg carriers account for about 10% of China's totalpopulation.Hepatitis B is transmitted mainly through the bloodstream, occasionally through saliva and semen, and in daily life, general contact is unlikely to infect others."Small Sanyang," who, usually without hepatitis symptoms, liver function has been normal people, also known as hepatitis B virus carriers.It is estimated that there are about 215 million people living with hepatitis B virus in the world, about 120 million of them in china.。
