Specimen Collection
Serum/ EDTA plasma obtained from all acute cases, diagnosed by positive IgM serology (in the absence of HAV vaccination in the preceding 12 weeks) or by detection of HAV by PCR/NAT. Minimum volume 0.25 mL. Where possible, a faecal specimen should also be collected. Minimum 0.25 g or 0.25 mL.
Diagnostic Use and Interpretation
Hepatitis A is a highly contagious liver infection caused by the hepatitis A (HAV) virus. The virus is transmitted through the faecal/oral route, usually through ingestion of contaminated food or water. Unlike hepatitis B and C, hepatitis A infection does not cause chronic liver disease. It is rarely fatal, but it can cause debilitating symptoms. Occasionally fulminant hepatitis may occus, which is associated with high mortality.
