A Hepatitis B Panel Test is a group of tests used to diagnose and monitor Hepatitis B virus (HBV) infection. The tests typically include:

1. HBsAg (Hepatitis B Surface Antigen) :
       – Indicates current HBV infection
       – Detected in acute and chronic infections
2. Anti-HBs (Hepatitis B Surface Antibody) :
       – Indicates immunity to HBV
       – Detected after vaccination or recovery from infection
3. Anti-HBc (Hepatitis B Core Antibody) :
       – Indicates past or current HBV infection
       – Detected in acute and chronic infections
4. HBeAg (Hepatitis B e-Antigen) :
       – Indicates viral replication and high infectivity
       – Detected in acute and chronic infections
5. Anti-HBe (Hepatitis B e-Antibody) :
       – Indicates reduced viral replication and lower infectivity
       – Detected in chronic infections
6. HBV DNA (Hepatitis B Viral Load) :
       – Measures the amount of HBV in the blood
       – Monitors treatment effectiveness

These tests help diagnose:

• Acute or chronic HBV infection
• Immunity to HBV
• Effectiveness of treatment
• Risk of liver damage or cancer

The Hepatitis B Panel Test is commonly used for:

• Routine screening
• Pre-employment testing
• Blood donation screening
• Pregnancy testing
• Monitoring liver function
