Understanding Lab Tests for Severe Hepatitis B infection
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Severe Hepatitis B infection is a serious viral liver disease that can cause significant liver damage and life-threatening complications. Blood tests are essential for diagnosing the infection, determining its severity, and monitoring the progression of the disease to guide appropriate treatment decisions.
Recommended Test
Hepatitis Be Antigen
This test measures the presence of Hepatitis Be Antigen (HBeAg) in the blood, which is a key marker for assessing the severity and infectivity of Hepatitis B. High levels of this antigen indicate active viral replication and suggest a severe form of infection that carries increased risk for serious complications including liver cirrhosis and liver cancer. This test is crucial for determining treatment urgency and monitoring disease progression.

Why Blood Testing is Critical for Hepatitis B
Hepatitis B infections can range from mild to severe, and blood tests are fundamental for assessing the severity of the infection and viral activity. These tests help healthcare providers determine the risk of complications such as liver cirrhosis, liver failure, or liver cancer, and guide treatment strategies.
Understanding Your Results
The presence and levels of Hepatitis Be Antigen provide valuable information about the activity of the virus and the potential for liver damage. Higher levels typically correlate with more active infection and greater risk of transmission to others. Regular monitoring through blood testing is essential for managing the condition effectively.
