Understanding Lab Tests for Hepatitis B Infection
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Hepatitis B is a viral infection that affects the liver, caused by the Hepatitis B virus (HBV). This serious condition can range from acute infection to chronic disease and requires specific blood tests for accurate diagnosis and monitoring of disease activity.
Recommended Test
Hepatitis Be Antigen
This test detects the presence of Hepatitis Be Antigen (HBeAg) in the blood, which indicates an active Hepatitis B infection. The presence of this antigen is often associated with higher levels of virus in the blood and greater infectivity, making it a crucial marker for assessing disease activity and transmission risk.

Diagnosing Hepatitis B Infection
Because Hepatitis B symptoms can be mild or absent in early stages, and may resemble other liver conditions or viral infections, blood testing is essential for definitive diagnosis. Laboratory tests can detect viral antigens, antibodies, and assess the level of viral activity in the body.
Understanding Your Results
A positive Hepatitis Be Antigen test indicates active viral replication and high infectivity. This information is vital for healthcare providers to determine appropriate treatment strategies and implement necessary precautions to prevent transmission to others.
