Overview

MONOLISA™ Anti-HBs EIA

Excellent Percent Agreement with Other Anti-HBs FDA Approved Assays

The percent agreement between the MONOLISA™ Anti-HBs EIA and the reference anti-HBs assays was evaluated for each specimen classification.

Percent Agreement: MONOLISA Anti-HBs EIA versus Reference Anti-HBs EIA

HBV Classification Total Number of Samples Positive Percent Agreement Negative Percent Agreement
Acute Infection 14 100.0% (1/1) 100.0% (13/13)
Chronic Infection 81 66.7% (4/6) 94.7% (71/75)
Early Recovery 107 75.0% (3/4) 85.4% (88/103)
Recovery 176 94.7% (160/169) 0.0% (0/3)
Recovered 12 0.0% (0/1) 0.0% (0/5)
Past Infection 96 94.8% (91/96) NA (0/0)
HBV Vaccine Response 316 97.2% (307/316) NA (0/0)
HBV Vaccine Response Status Indeterminate 32 0.0% (0/7) 5.9% (1/17)
Not Previously Infected 609 NA (0/0) 98.2% (598/609)
Uninterpretable 9 100.0% (1/1) 100.0% (8/8)
TOTAL 1452 94.3% (567/601) 93.5% (779/833)


The positive percent agreement with the reference method is 94.3% (567/601) with a 95% confidence interval of 92.2–95.9%. The negative percent agreement with the reference method is 93.5% (779/833) with a 95% confidence interval of 91.6–95.0%.
The 18 specimens that were indeterminate by both assays were not included in the percent agreement calculations.

Excellent Correlation with the Official WHO Reference Standard Panel

Dilutions of the WHO First International Reference Preparation for Antibody to HBsAg (1977) were run in the Bio-Rad MONOLISA Anti-HBs quantitative assay. A linear regression of the mean anti-HBs EIA result versus the calculated concentration of each WHO dilution was used to determine the anti-HBs concentration.

Quantification and Wide Calibration Range: MONOLISA Anti-HBs Calibrator Kit

MONOLISA Anti-HBs Calibrator Kit allows measurement of a wide range of values in a calibration curve from 0 to 1000 mIU/mL without the need for dilution of high-titer samples.

MONOLISA™ Anti-HBs EIA is for the qualitative and quantitative detection of antibodies to hepatitis B surface antigen (anti-HBs) in human serum or plasma. The MONOLISA™ Anti-HBs EIA is intended for manual use and for use with the Bio-Rad EVOLIS™ Automated Microplate System in the detection of antibodies to hepatitis B surface antigen.

Bio-Rad offers a full range of sensitive and specific hepatitis B microplate assays to detect every stage of hepatitis B virus (HBV) infection. All Bio-Rad hepatitis B enzyme immunoassays (EIA) feature common reagents and procedures for use with other Bio-Rad assays, fast incubation time (2.5 hours), and easy automation. Advanced safety features include: barcoded reagents, color-coded reagents and reagent labels, microplate strip identification, color monitoring for sample and conjugate addition steps, and color changes during protocol steps.
