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 The last 3 digits -190 have been replaced by -119 for logistic purposes.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.

R2 HBsAg~Ru(bpy)32+, 1 bottle, 15.8 mL:HBsAg (ad/ay) human/recombinant, labeled with ruthenium complex > 0.3 mg/L; MES buffer 85 mmol/L, pH 6.5; preservative.b) MES = 2-morpholino-ethane sulfonic acidAHBS 2 Cal1 Calibrator 1, 1 bottle of 1.3 mL:Anti ‑HBs (human) in human serum; preservative.AHBS 2 Cal2 Calibrator 2, 1 bottle of 1.3 mL:Anti ‑HBs (human) in human serum; preservative.Precautions and warnings For in vitro diagnostic use.Exercise the normal precautions required for handling all laboratory reagents. 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).
