ADDITIONAL INFORMATION: Anti-HBc IgM can be detected in 100% of patients within the first month of illness. The antibody will persist for a variable time period but 96% of patients will become negative by 6 months and 98% negative by 9-12 months. Therefore, this test can only be used for the diagnosis of acute Hepatitis B and NOT to determine the immune status of a patient. Anti-HBc IgM may also be present in acute Hepatitis B in the absence of HBsAg.
