Hepatitis A virus – IgM Antibodies (HAV IgM)
Anti-HAV IgM becomes detectable in the blood within 2 weeks after infection, persisting at elevated levels for about 2 months before declining to undetectable levels by 6 months. However, sensitive immunoassays may occasionally detect anti-HAV IgM for up to 1 year after acute hepatitis A.
If your test is positive or reactive, it may mean: You have an active HAV infection. You have had an HAV infection in the past. You have gotten the hepatitis A vaccine.
Specimens with signal to cutoff (S/CO) values ≥ 1.21 are considered reactive for IgM anti-HAV. Specimens with S/CO values of 0.80 to < 1.21 are considered indeterminate and specimens with S/CO values < 0.80 are considered nonreactive.
Hepatitis A is an inflammation of the liver that can cause mild to severe illness. The hepatitis A virus (HAV) is transmitted through ingestion of contaminated food and water or through direct contact with an infectious person. Almost everyone recovers fully from hepatitis A with a lifelong immunity.
