Hepatitis B e (Envelop) Antigen (HbeAg)
What is HbeAg?
The Hepatitis B e Antigen test is performed to diagnose an infection of Hepatitis B Virus. It is also performed as a part of a panel of tests for Hepatitis B to find out if the infection has been acquired recently. Patients who test positive for Hepatitis B e Ag are more infectious as compared to Hepatitis B e Ag negative patients. During recovery from acute hepatitis B, HBeAg level declines and becomes undetectable in the serum, while hepatitis B e-antibody (anti-HBe) appears and becomes detectable in the serum.
Why is HbeAg done?
- When symptoms of acute hepatitis appear, which include fever, fatigue, joint pain, dark coloured urine and pale coloured stool, jaundice, etc.
- When the patient is suspected of being exposed to HBV
Preparation for HbeAg
- No special preparation required
