The HBeAg test is a blood test that measures the presence of the Hepatitis B e-Antigen (HBeAg), a viral protein produced by the Hepatitis B virus. This antigen's presence in the blood indicates active viral replication.
Understanding the HBeAg Test
Here's a breakdown of what the HBeAg test entails:
- What it Measures: The test specifically detects the Hepatitis B e-Antigen.
- This antigen is released by infected liver cells into the bloodstream.
- Significance: The presence of HBeAg in the blood signifies that the Hepatitis B virus is actively multiplying. The more HBeAg, generally, the higher the level of active viral replication.
- Active Replication Indicator: The primary purpose of the HBeAg test is to evaluate how much virus is present in the blood.
- Clinical Relevance:
- A positive HBeAg test indicates high viral load and infectivity.
- Monitoring HBeAg levels helps in assessing the course of the infection and response to antiviral treatments.
Key Points
Here's a summary of the test:
| Aspect | Description |
|---|---|
| Test Name | HBeAg (Hepatitis B e-Antigen) Test |
| What it Detects | Hepatitis B e-Antigen, a viral protein |
| Meaning of Positive Result | Indicates active viral replication and high viral load |
| Clinical Use | Monitors disease progression, assesses infectivity and response to treatment |
In simple terms:
The HBeAg test helps doctors understand how much Hepatitis B virus is actively multiplying in the body of a person infected with the virus. It acts as a marker of active disease and helps in the management of the infection.
