Elecsys Anti-HBs IIREFSYSTEM********************** 300cobas e 801EnglishSystem information Short name ACN (application code number) AHBS 2 10138 Immunoassay for the in vitro quantitative determination of human antibodies to the hepatitis B surface antigen (HBsAg) in human serum and plasma.Anti-HBs assays are used within the scope of hepatitis B vaccination to check the necessity and success of vaccination. In addition, anti-HBs assays are used to monitor the course of disease following acute hepatitis B infection. This test is not intended for diagnosis.The e lectro c hemi l uminescence i mmuno a ssay “ECLIA” is intended for use on the cobas e 801 immunoassay analyzer.Note: Please note that the catalogue number appearing on the package insert retains only the first 8 digits of the licensed 11-digit Catalogue Number: 07026854190 for the Elecsys Anti-HBs II assay. The last 3 digits -190 have been replaced by -119 for logistic purposes. SummaryAnti-HBs is a specific (generally IgG) antibody that is directed against the hepatitis B surface antigen (HBsAg).1,2 Anti ‑HBs can be detected several weeks after the disappearance of hepatitis B surface antigen.3,4 Anti ‑HBs can be formed following a hepatitis B infection or after hepatitis Bvaccination.3,4 Antibodies are formed against the HBsAg determinant a, which is common to all subtypes, and against subtype-specific determinants.1,5,6Anti ‑HBs assays are used within the scope of hepatitis B vaccination to check the necessity and success of vaccination.2,4,7 In addition, anti ‑HBs assays are used to monitor the course of disease following acute hepatitis B infection.3The Elecsys Anti ‑HBs II assay uses a mixture of purified antigens fromhuman serum (HBsAg subtype ad), and recombinant HBsAg subtype ay from CHO (Chinese Hamster Ovary) cells. Test principleSandwich principle. Total duration of assay: 18 minutes.▪ 1st incubation: Anti ‑HBs in the sample (24 μL), biotinylated HBsAg(ad/ay), and HBsAg (ad/ay) labeled with a ruthenium complex a) react to form a sandwich complex.▪ 2nd incubation: After addition of streptavidin-coated microparticles, thecomplex becomes bound to the solid phase via interaction of biotin and streptavidin.▪ The reaction mixture is aspirated into the measuring cell where themicroparticles are magnetically captured onto the surface of the electrode. Unbound substances are then removed with ProCell II M. Application of a voltage to the electrode then induces chemiluminescent emission which is measured by a photomultiplier.▪ Results are determined via a calibration curve which is instrument-specifically generated by 2‑point calibration and a master curve provided via the cobas link.a) Tris(2,2'-bipyridyl)ruthenium(II)-complex (Ru(bpy)32+)Reagents – working solutionsThe cobas e pack (M, R1, R2) is labeled as AHBS 2.

Disposal of all waste material should be in accordance with local guidelines. Safety data sheet available for professional user on request.This kit contains components classified as follows in accordance with the Regulation (EC) No. 1272/2008:n ‑Octyl ‑N,N ‑dimethyl ‑3‑ammonio ‑1‑propanesulfonateEUH 208 May produce an allergic reaction.Product safety labeling primarily follows EU GHS guidance. All human material should be considered potentially infectious.The calibrators (AHBS 2 Cal1 and AHBS 2 Cal2) have been preparedexclusively from the blood of donors tested individually and shown to be free from HBsAg and antibodies to HCV and HIV. The testing methods applied were FDA ‑approved or cleared in compliance with the European Directive 98/79/EC, Annex II, List A.The HBsAg starting material used was inactivated prior to labeling with biotin or ruthenium by heating to 60 °C for 15 hours. In addition, any virus particles remaining were removed by ultracentrifugation.However, as no inactivation or testing method can rule out the potential risk of infection with absolute certainty, the material should be handled with the same level of care as a patient specimen. In the event of exposure, the directives of the responsible health authorities should be followed.8,9 Avoid foam formation in all reagents and sample types (specimens, calibrators and controls). Reagent handlingThe reagents (M, R1, R2) in the kit are ready-for-use and are supplied in cobas e packs. CalibratorsThe calibrators are supplied ready ‑for ‑use in bottles compatible with the system.Unless the entire volume is necessary for calibration on the analyzer, transfer aliquots of the ready ‑for ‑use calibrators into empty snap ‑cap bottles (CalSet Vials). Attach the supplied labels to these additional bottles. Store the aliquots at 2‑8 °C for later use.Perform only one calibration procedure per aliquot.All information required for correct operation is available via the cobas link. Storage and stability Store at 2‑8 °C. Do not freeze.Store the cobas e pack upright in order to ensure complete availability of the microparticles during automatic mixing prior to use. Stability of the cobas e pack: unopened at 2‑8 °Cup to the stated expiration date on the cobas e 801 analyzer 16 weeksStability of the calibrators: unopened at 2‑8 °C up to the stated expiration date after opening at 2‑8 °C 16 weeks on the cobas e 801 analyzer at 20‑25 °Cuse only onceadhering to the snap ‑cap.Specimen collection and preparationOnly the specimens listed below were tested and found acceptable.Serum collected using standard sampling tubes or tubes containing separating gel.K2‑EDTA and K3‑EDTA plasma.Criterion: Slope 1.00 ± 0.15 + intercept 0 ± 2 IU/L + bias at 10 IU/L: ≤ 30 %. Stable for 3 days at 20‑25 °C, 6 days at 2‑8 °C, 3 months at ‑20 °C(± 5 °C). The samples may be frozen 5 times.For plasma treated with lithium heparin, lithium heparin with gel or sodium heparin, the values found were on average up to 20 % lower than those obtained in serum. For plasma treated with sodium citrate, the values found were on average up to 30 % lower than those obtained with serum.The sample types listed were tested with a selection of sample collection tubes or systems that were commercially available at the time of testing, i.e. not all available tubes of all manufacturers were tested. Sample collection systems from various manufacturers may contain differing materials which could affect the test results in some cases. When processing samples in primary tubes (sample collection systems), follow the instructions of the tube manufacturer.Centrifuge samples containing precipitates and thawed samples before performing the assay.Do not use heat‑inactivated samples.Do not use samples and controls stabilized with azide.Ensure the samples and calibrators are at 20‑25 °C prior to measurement. Due to possible evaporation effects, samples and calibrators on the analyzers should be analyzed/measured within 2 hours.The performance of the Elecsys Anti‑HBs II assay has not been established with cadaveric samples or body fluids other than serum and plasma.

Refer to the appropriate operator’s manual for analyzer‑specific assay instructions.Resuspension of the microparticles takes place automatically prior to use. Place the cooled (stored at 2‑8 °C) cobas e pack on the reagent manager. Avoid foam formation. The system automatically regulates the temperature of the reagents and the opening/closing of the cobas e pack. Calibrators:Place the calibrators in the sample zone.Read in all the information necessary for calibrating the assay.CalibrationTraceability: This method has been standardized against the 1st WHO Reference Standard 1977.The predefined master curve is adapted to the analyzer using AHBS 2 Cal1 and AHBS 2 Cal2.Calibration frequency: Calibration must be performed once per reagent lot using AHBS 2 Cal1, AHBS 2 Cal2 and fresh reagent (i.e. not more than24 hours since the reagent kit was registered on the analyzer).Renewed calibration is recommended as follows:▪after 12 weeks when using the same reagent lot▪after 28 days when using the same cobas e pack on the analyzer▪as required: e.g. quality control findings with PreciControl Anti‑HBs outside the defined limitsQuality controlFor quality control, use PreciControl Anti‑HBs.Controls for the various concentration ranges should be run individually at least once every 24 hours when the test is in use, once per cobas e pack, and following each calibration.The control intervals and limits should be adapted to each laboratory’s individual requirements. Values obtained should fall within the defined limits. Each laboratory should establish corrective measures to be taken if values fall outside the defined limits.If necessary, repeat the measurement of the samples concerned.Follow the applicable government regulations and local guidelines for quality control.CalculationThe analyzer automatically calculates the analyte concentration of each sample in IU/L.Interpretation of the resultsNumeric result Result message Interpretation< 10 IU/L Non-reactive Negative for anti-HBs≥ 10 IU/L Reactive Positive for anti-HBsvary depending on the testing procedure used. Results obtained from a single sample using tests from different manufacturers can therefore differ by up to a factor of 4 (or even a factor of 10 in rare cases). If there is a change in the assay procedure used during the monitoring of vaccination protection, then the anti‑HBs values obtained upon changing over to the new method must be confirmed by parallel measurements by both methods. Vaccination strategies in certain risk groups are based on the measured anti‑HBs concentration. Respective recommendations are given by national or regional guidelines. Limitations - interferenceThe effect of the following endogenous substances and pharmaceutical compounds on assay performance was tested. Interferences were tested up to the listed concentrations and no impact on results was observed. Endogenous substancesCompound Concentration testedBilirubin ≤ 513 μmol/L or ≤ 30 mg/dL Hemoglobin ≤ 0.621 mmol/L or ≤ 1000 mg/dL Intralipid ≤ 1500 mg/dLBiotin ≤ 41 nmol/L or ≤ 10 ng/mL Rheumatoid factors ≤ 1200 IU/mLAlbumin ≤ 7.0 g/dLIgG ≤ 7.0 g/dLIgA ≤ 1.6 g/dLIgM ≤ 1.0 g/dL2 / 42017-09, V 1.0 Can EnglishCriterion: Recovery for samples from Limit of Detection to 10 IU/L:≤ ± 2 IU/L, and samples > 10 IU/L: ≤ ± 20 % of initial value.Samples should not be taken from patients receiving therapy with high biotin doses (i.e. > 5 mg/day) until at least 8 hours following the last biotin administration.Pharmaceutical substancesIn vitro tests were performed on 16 commonly used pharmaceuticals. No interference with the assay was found.In addition, the following special drugs used in hepatitis B therapy were tested. No interference with the assay was found.Special drugsDrug Concentration testedmg/LPeginterferon alfa‑2a ≤ 0.18Peginterferon alfa‑2b ≤ 1.6Lamivudine ≤ 300Adefovir ≤ 10Entecavir ≤ 10Tenofovir ≤ 600Telbivudine ≤ 245Due to high-dose hook effect c), results from anti‑HBs concentrations of> 200000 IU/L may be found below the upper limit of the measuring range of 1000 IU/L. In rare cases, a high-dose hook effect from anti HBs concentrations of < 20000 IU/L cannot be excluded. Therefore in case of any unexpected low result the sample should be diluted 1:100 (refer to chapter “Dilution”) and tested again.In rare cases, interference due to extremely high titers of antibodies to streptavidin and ruthenium can occur. The test contains additives which minimize these effects.c) High-dose hook effect: A sample with a true concentration clearly above the measuring range, but found within the measuring range.Limits and rangesMeasuring range2‑1000 IU/L (defined by the Limit of Detection and the maximum of the master curve). Values below the Limit of Detection are reported as< 2 IU/L.Values above the measuring range are reported as > 1000 IU/L (or up to 100000 IU/L for 100‑fold diluted samples).DilutionSamples with anti‑HBs concentrations above the measuring range can be diluted with Diluent Universal. The recommended dilution is 1:100 (either automatically by the analyzer or manually). The concentration of the diluted sample must be > 10 IU/L.After manual dilution, multiply the result by the dilution factor.After dilution by the analyzer, the software automatically takes the dilution into account when calculating the sample concentration.Manual dilution can also be made with negative human serum.Note: Antibodies to HBsAg are heterogeneous. In some isolated cases, this may lead to non-linear dilution behavior.Specific performance dataRepresentative performance data on the analyzer is given below. Results obtained in individual laboratories may differ.PrecisionPrecision was determined using Elecsys reagents, samples and controls in a protocol (EP05‑A3) of the CLSI (Clinical and Laboratory Standards Institute): 2 runs per day in duplicate each for 21 days (n = 84).

罗氏E601 电化学发光免疫分析仪双向通讯软件的的开发
发表时间:2016-01-26T14:25:22.000Z 来源:《卫生部公告》2015年9期作者:黄阶胜顾向明李莹莹[导读] 广东省中山市中医院检验科 RS232通讯根据仪器的不同,主要有两种方式:单向通信、双向通信。
(广东省中山市中医院检验科广东中山 528400) 摘要:探讨了PowerBuilder 9.0 环境下实现医学检验仪器与计算机双向通信的方法,详细介绍了如何利用PowerBuilder 9.0 来开发罗氏E601 电化学发光免疫分析仪双向通迅软件。
关键词:PowerBuilder 9.0;双向通迅;电化学发光免疫分析实验室信息系统(LIS)对医学检验仪器数据的获取主要通过串行口通讯、USB端口通讯、TCP/IP通讯、打开数据库或文本文件直接读取等几种方法,其中通过串行口通信是最主要的方式,医学检验仪器大多都支持RS232标准。
RS232通讯根据仪器的不同,主要有两种方式:单向通信、双向通信。
单向通信:检验数据由仪器向LIS工作站单向传送,仪器只能传送分析数据,不能接受由LIS发出的任何指令。
双向通信:与单向通信不同,信息不仅从仪器向LIS工作站传送,仪器也能接受从LIS传送的各种指令。
双向通讯是效率最高的检验设备与实验室信息系统(LIS)的通讯模式,它的应用进一步优化了检验流程,提高了检验技师的工作效率,有效避免了检验样本与病人信息匹配错误的现象,减少了医疗差错。
下面详细介绍了利用PowerBuilder 9.0来设计罗氏E601电化学发光免疫分析仪双向通迅程序。
1 Microsoft comm控件简介
Microsoft comm控件有许多重要的属性和事件,下面给出部分常用的属性: CommPort:设置并返回通信端口号;
Settings:设置并返回波特率、校验位、数据位、停止位; PortOpen:设置并返回端口状态,也可以用于打开和关闭串口; OutBufferSize:设置并返回发送缓冲区的大小,以字符为单位; InBufferSize:设置并返回接收缓冲区的大小,以字符为单位; SThreshold:设置并返回发送时产生ONComm 事件的字符数; RThreshold:设置并返回接收时产生ONComm 事件的字符数; InputMode:设置并返回接收类型;
InputLen:设置并返回从接收缓冲区读取的字符; Input:返回和删除接收缓冲区的字符; Output:写字符串到发送缓冲区;
CommEvent:返回最近的通信事件或错误; OnComm事件:无论何时当CommEvent属性的值变化时,就产生OnComm事件,标志发生了一个通信事件或一个错误。
2 罗氏E601电化学发光免疫分析仪与计算机串口联线
罗氏E601电化学发光免疫分析仪与计算机串口联线如下图仪器端与计算机都为9孔母头,仪器端3和计算机端2对接,仪器端2和计算机端3对接,仪器端5和计算机端5对接,仪器端7和8短接,计算机端7和8短接,计算机端4和6短接。
3 罗氏E601电化学发光免疫分析仪设置
选择页面“综合功能”,然后选择子页面“系统”,把“条形码设置”中的“常规/急诊”设为“是”。
在“系统”画面上点击“通讯传输”按钮即可弹出窗口,选择子页面“通讯设置”中将“ 波特率” 设为“ 9600 ” , 将“ 奇偶校验位” 设为“8Bit,NONE,1StopBit”,选择子页面“内容设置”,在“只传结果”前不要打勾,其它选项都打上勾。
4 双向通讯主要代码
本双向通信程序由PowerBuilder 9.0软件编写, 在通信窗口中插入mscomm32.ocx通信控件,控件名为ole_mscomm。
初始化程序放在窗口的open()事件中。
窗口的open()事件程序主要如下: ole_mport = 1 //设置通信端口号为com1ole_mscomm.object.settings = “ 9600,n,8,1 ” // 波特率为9600bps,无奇偶校验,8 位数据位,1位停止位。
if ole_mscomm.object.portopen = false then ole_mscomm.object.portopen = true //打开串口timer(5) 数据处理放在窗口的timer()事件中。
窗口的timer()事件程序主要如下: string ls_inputdata //读取的数据
Boolean ib_iseot = false
string is_enq = char(5), is_ack = char(6) string is_buffer, is_send, ls_sendxm
integer is_number, i,li_inputdatalens, li_pos ls_inputdata = ole_mscomm.object.input
li_inputdatalens = len(ls_inputdata)
for i = 1 to li_inputdatalens
choose case mid(ls_inputdata,i,1)
case char(0) ,char(2) ,char(10) //过滤case char(1)
ib_iseot = false //初始化
ole_mscomm.object.output = is_ack //应答ackcase char(3),char(5)
ole_mscomm.object.output = is_ack //应答ackcase char(4)
is_buffer = is_buffer + char(4)
ole_mscomm.object.output = is_enq //应答enqcase char(6)
if ib_iseot = false then
is_buffer = is_buffer + char(6)
li_pos = pos(is_send,';')
if li_pos > 0 then
if is_number = 2 then
ls_sendxm = mid(is_send,li_pos + 1,Len(is_send) - li_pos)
ole_mscomm.object.output = ls_sendxm //向仪器发送测试指令
ib_iseot = trueend if
if is_number = 1 then
ls_sendxm = mid(is_send,1,li_pos - 1)
ole_mscomm.object.output = ls_sendxm //向仪器发送测试指令
is_number = is_number + 1end ifelse
ls_senddata = is_send
ole_mscomm.object.output = ls_sendxm //向仪器发送测试指令
ib_iseot = trueend ifelse
ole_mscomm.object.output = is_eot
ib_iseot = falseend ifcase char(13)
if len(is_buffer) > 2 then
if mid(is_buffer,len(is_buffer) - 2,1) <> char(23) then
this.wf_data(is_buffer) //结果数据处理
is_buffer = ''end ifelse
is_buffer = ''end ifcase char(23) //eot
is_buffer = is_buffer + char(23)
ole_mscomm.object.output = is_ack //应答case else
is_buffer = is_buffer + mid(ls_inputdata,i,1)end choosenext
