Details
Hepatitis B Core Antibody, Total, with Reflex to IgM - This assay detects presence of both IgG and IgM antibodies to the hepatitis B core (anti-HBc) antigen. If positive, it reflexes to further detect only the presence of IgM anti-HBc. When both the total anti-HBc and IgM anti-HBc are positive, it is indicative of acute HBV infection. A positive total anti-HBc with negative IgM anti-HBc is indicative of either acute or past Hepatitis B infection. Total anti-HBc may be the only HBV marker detected in past infection. Anti-HBc antibodies, both total and IgM, are absent from HBV vaccinated people.
Reflex testing uses predefined clinical logic to automatically order one or more follow-up tests based on the initial test results. Reflex tests are performed automatically without the intervention of the ordering practitioner. They are conducted using the same sample your Patient already provided. If reflex tests are required, there will be additional charges.
