Hepatitis B core antibodies (HBcAb) appear shortly after the onset of symptoms of hepatitis B infection and soon after the appearance of hepatitis B surface antigen (HBsAg). Initially, HBcAb consist almost entirely of the IgM class, followed by the appearance of anti-HBc IgG, for which there is no commercial diagnostic assay.
The HBc total antibodies test, which detects both IgM and IgG antibodies, and the test for HBc IgM antibodies may be the only markers of a recent hepatitis B infection detectable in the "window period." The window period begins with the clearance of HBsAg and ends with the appearance of antibodies to hepatitis B surface antigen). HBc total Ab may be the only serologic marker remaining years after exposure to hepatitis B.
This assay is FDA-approved for in vitro diagnostic use and not for screening cell, tissue, and blood donors.

Interpretation
Provides information to assist in interpretation of the test results
Provides information to assist in interpretation of the test results
Negative anti-hepatitis B core (HBcAb) total test results indicate the absence of exposure to hepatitis B virus and no evidence of recent, past/resolved, or chronic hepatitis B.
A positive result indicates acute, chronic, or past or resolved hepatitis B.
An inconclusive result suggests the presence of an interfering substance in the patient's serum specimen.
Positive HBcAb total test results should be correlated with the presence of other hepatitis B virus serologic markers, elevated liver enzymes, clinical signs and symptoms, and a history of risk factors.
If clinically indicated, testing for HBIM / Hepatitis B Core Antibody, IgM, Serum is necessary to confirm an acute or recent infection.
Neonates (<1 month old) with positive HBcAb total results from this assay should be tested for HBcAb IgM (HBIM / Hepatitis B Core Antibody, IgM, Serum) to rule out possible maternal HBcAb causing false-positive results. Repeat testing using this assay for HBcAb total within one month is also recommended in these neonates.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Samples containing sodium azide may cause false positive results and should not be tested.
Lipemic and precipitated samples may give inconsistent results.

Method Description

Describes how the test is performed and provides a method-specific reference
The VITROS anti-hepatitis B core (anti-HBc) assay is a competitive immunoassay method based on the reaction of anti-HBc in the sample with hepatitis B core antigen (HBcAg)-coated wells. Unbound sample is removed by washing. Horseradish peroxidase (HRP)-labeled antibody conjugate (mouse monoclonal anti-HBc) is then allowed to react with the remaining exposed HBcAg on the well surface. Unbound conjugate is removed by washing.
The bound HRP conjugate is measured by a luminescent reaction. A reagent containing luminogenic substrates (a luminol derivative and a peracid salt) and an electron transfer agent are added to the wells. The HRP in the bound conjugate catalyzes the oxidation of the luminol derivative, producing light. The electron transfer agent increases the level and duration of the light produced. The light signals are read by the system. The amount of HRP conjugate bound is indicative of the concentration of anti-HBc present in the sample.(Package insert: VITROS Anti-HBc Assay, Pub. No. GEM1211, version 14.1. Ortho-Clinical Diagnostics, Inc; 09/06/2019)
