Hepatitis B e Antigen and Antibody Testing: Do You Need Further Tests? - Gastroenterology and Hepatology

Understanding Hepatitis B e Antigen (HBeAg) and Antibody Testing is crucial for managing Hepatitis B infection and determining the appropriate follow-up and treatment. In your case, you are a Hepatitis B carrier with a recent health check showing normal liver enzyme levels (GOT, GPT, r-GT) and a normal abdominal ultrasound. Your HBeAg result is negative, which indicates that you are not in an active phase of viral replication.

The relationship between HBeAg and anti-HBe (Hepatitis B e antibody) is significant. Typically, when HBeAg is negative, it suggests that the virus is less active, and the immune system is controlling the infection. In many cases, this would correlate with the presence of anti-HBe, indicating that the body has developed an immune response against the virus. However, it is important to note that while the presence of HBeAg is often associated with active viral replication, its absence does not automatically guarantee that anti-HBe is positive. There can be exceptions, particularly in cases where the immune response is not fully developed or if there are mutations in the virus.

The laboratory technician's assertion that if HBeAg is negative, anti-HBe will be positive is generally correct but not absolute. It is advisable to confirm the presence of anti-HBe through testing, especially since you are a carrier. The presence of anti-HBe would indicate a lower risk of liver disease progression and a better prognosis. If anti-HBe is negative, further evaluation may be warranted to assess the viral load (HBV DNA) and determine if any treatment is necessary.

Regarding your liver function tests (GOT, GPT, r-GT), the values you provided fall within the normal range, which is reassuring. However, regular monitoring is essential for Hepatitis B carriers, as liver function can change over time. The alpha-fetoprotein (AFP) level you mentioned is also within normal limits, which is a good sign as elevated AFP can indicate liver cancer or significant liver damage.

In summary, while your current health indicators are positive, it is prudent to test for anti-HBe to gain a complete understanding of your Hepatitis B status. This will help clarify your immune response to the virus and guide any necessary follow-up actions. Regular monitoring and consultations with a healthcare provider specializing in liver diseases are essential to ensure your long-term health and to address any potential complications associated with being a Hepatitis B carrier.
