Study Notes
Hepatitis A Markers
- Anti-HAV (IgM): Essential for diagnosing acute hepatitis A; detects the presence of IgM antibodies to HAV.
- Anti-HAV (IgG): Signifies past infection or vaccination; provides immunity and protection against future infections.
Hepatitis B Markers
- HBsAg: Presence indicates active hepatitis B infection; a critical marker on the surface of the hepatitis B virus (HBV).
- Anti-HBs: Reflects immunity to hepatitis B, acquired either through vaccination or after recovery from the infection.
- HBcAg: Found within the core of the HBV; represents a specific marker for hepatitis B.
-
Anti-HBc: Indicates prior exposure to HBV. Distinction between:
- IgM Anti-HBc: Suggests recent or acute infection.
- IgG Anti-HBc: Suggests past exposure or chronic infection; may be the only marker during the window period when HBsAg is not detectable.
Additional Markers for Hepatitis B
- HBeAg: Indicates active viral replication; associated with high viral load, increased transmissibility, and poorer patient prognosis.
- Anti-HBe: Presence indicates lower levels of viral replication, correlating with reduced transmissibility of HBV.
