HBeAg (Hepatitis B e Antigen) Test
Introduction
Hepatitis B e Antigen (HBeAg) is a protein secreted during HBV replication. Its presence usually indicates active viral replication and high infectivity, making it a crucial marker in Hepatitis B diagnosis and staging.
Why Take an HBeAg Test?
- Infectivity assessment: HBeAg positivity suggests high transmission risk.
- Viral replication evaluation: Often interpreted with HBV DNA results.
- Disease staging: Helps classify phases of chronic Hepatitis B, such as immune tolerant or active phases.
- Treatment monitoring: Used to assess the effectiveness of antiviral therapy.
Method & Workflow
A venous blood sample is tested for HBeAg levels. Results are analyzed along with HBsAg, HBV DNA, and liver function tests.
Who Should Consider Testing?
- Patients diagnosed or suspected with Hepatitis B
- HBV carriers needing infectivity evaluation
- Patients undergoing antiviral therapy
- Individuals preparing for premarital, prenatal, or occupational health checks
Frequently Asked Questions (FAQ)
Q1: What does a positive HBeAg mean?
A: It indicates active HBV replication and high infectivity.
Q2: Does a negative HBeAg mean no infectivity?
A: Not necessarily. Some patients may still have high HBV DNA levels despite negative HBeAg.
Q3: How is HBeAg related to HBV DNA testing?
A: HBeAg reflects replication activity, while HBV DNA directly quantifies viral load. Both are commonly used together.
