Test Code HBCSN Hepatitis B Virus Core Total Antibodies Screen, Serum


Ordering Guidance


This test should not be used to test symptomatic individuals (ie, diagnostic purposes) suspected with viral hepatitis. For testing such patients with or without risk factors for hepatitis B virus (HBV) infection, order HBC / Hepatitis B Virus Core Total Antibodies, Serum.

 

This test should not be used to screen or test pregnant individuals with or without risk factors for HBV. For testing such patients, order HBCPR / Hepatitis B Virus Core Total Antibodies Prenatal, Serum.

 

If a hepatitis B core total antibody test that reflexes to hepatitis B core IgM is needed, order CORAB / Hepatitis B Virus Core Total Antibodies, with Reflex to Hepatitis B Virus Core Antibody IgM, Serum.

Useful For

Diagnosis of recent or past hepatitis B

 

Determination of occult hepatitis B in otherwise healthy hepatitis B virus carriers with negative test results for hepatitis B surface (HBs) antigen, anti-HBs, anti-hepatitis B core IgM, hepatitis Be (HBe) antigen, and HBe antibody

 

This assay is not useful for differentiating between acute, chronic, past, or resolved hepatitis B.

 

This test should not be used as a screening or confirmatory test for blood donor specimens.

Interpretation

Negative hepatitis B virus core total antibody (anti-HBc 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.

 

Positive anti-HBc 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 anti-HBc IgM (HBIM / Hepatitis B Virus Core Antibody, IgM, Serum) is necessary to confirm an acute or recent infection.

 

Neonatal patients (<1 month old) with positive anti-HBc total results from this assay should be tested for anti-HBc IgM (HBIM / Hepatitis B Virus Core Antibody, IgM, Serum) to rule out possible maternal anti-HBc causing false-positive results. Repeat testing using this assay for anti-HBc total within 1 month is also recommended for these neonatal patients.
