Hepatitis B Exams & Tests


Since many people with hepatitis B don t have symptoms, detection of the virus sometimes occurs during routine medical exams or blood work that shows elevated liver enzymes due to liver damage, low albumin levels, or prolonged prothrombin time due to severe liver failure.

Tests that may be conducted to confirm hepatitis B include:

  • Hepatitis B surface antigen (HBsAg) is the outer surface of the virus. It usually disappears from the blood in 1-2 months.
  • Hepatitis B core antibody (Anti-HBc) is usually detected within 1-2 weeks of the appearance of hepatitis B surface antigen.
  • Hepatitis B surface antibody (Anti-HBs) is found both in those who have been immunized and those who have recovered from hepatitis infection.



If tests confirm the presence of hepatitis B, your health care provider may perform more tests to check the severity of the infection as well as the health of your liver. Tests may include:
  • E-antigent test - detects the levels of the virus in your blood.
  • Liver enzymes - check for elevated levels of liver enzymes.
  • Alpha-fetoprotein (AFP) test - detects potential liver cancer.
  • Liver ultrasound or CT scan - looks at the liver for cirrhosis (scarring) or liver cancer.
  • Liver biopsy - liver tissue is removed for microscopic analysis.
