Introduction

Hepatitis B refers to hepatitis B virus (HBV) infection. The presence of hepatitis B antibodies does not necessarily indicate the absence of hepatitis B and must be evaluated according to specific circumstances. Having hepatitis B antibodies usually means protective antibodies are present, indicating either a past HBV infection that has resolved with subsequent recovery, or successful vaccination against hepatitis B, resulting in the production of protective antibodies that help protect the body from future HBV infection.

Generally speaking, "hepatitis B" refers to hepatitis B virus (HBV) infection. Whether having antibodies against hepatitis B indicates the absence of hepatitis B depends on the specific circumstances. Detailed analysis is as follows:

1. Yes

The presence of hepatitis B antibodies usually refers to protective antibodies, indicating either a past infection with the hepatitis B virus that has since resolved, or successful vaccination against hepatitis B, resulting in the production of protective antibodies that help prevent future HBV infection.

2. No

However, if a person has both hepatitis B surface antibody and hepatitis B surface antigen present, this does not necessarily rule out an active hepatitis B infection. Only when the hepatitis B surface antigen test is negative can it generally be concluded that there is no current hepatitis B infection.

Regular check-ups are recommended. If any abnormalities are detected, prompt medical consultation is advised to avoid delays in diagnosis and treatment.

What virus is HBsAg?

HBsAg is a viral marker produced after hepatitis B virus infection. It is not the virus itself, but rather a protein component found on the outer surface of the hepatitis B virus. In daily life, it is important to protect liver health by maintaining regular作息 (daily routines), avoiding excessive fatigue, and allowing sufficient time for liver cell repair. A light and balanced diet is recommended, with reduced intake of high-fat, high-sugar, and irritating foods to lessen the metabolic burden on the liver.

When should the third dose of the vaccine be administered, after how many months?

In general, the timing for the third dose of a vaccine varies depending on the vaccine type. For COVID-19 vaccines, the third dose is typically administered 6 months after completing the second dose. Other vaccines, such as hepatitis B and HPV vaccines, follow fixed schedules, so the specific vaccine type must be considered to determine the appropriate interval. Before vaccination, individuals can check the vaccine type and recommended intervals through vaccination sites or official channels, and complete the vaccination on schedule.

What does a five-item blood liver function test check for?

The five-item liver function blood test generally includes examination of hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B e-antigen, hepatitis B e-antibody, and hepatitis B core antibody. Hepatitis B surface antigen is a protein from the outer shell of the hepatitis B virus. Although it is not infectious by itself, its presence usually indicates the existence of the hepatitis B virus and serves as a marker for hepatitis B infection. A positive result suggests possible hepatitis B infection.

What Chinese herbs can completely cure "small three positives" (HBeAb, HBsAb, and HBcAb positive in hepatitis B)?

There is currently no traditional Chinese medicine that can completely cure "minor three positives" (a pattern of hepatitis B virus markers), but certain herbal medicines may help alleviate symptoms and regulate the immune system. Commonly used medications include Hugan Pian, Anluo Huaxian Wan, Yexiazhu Capsules, and Yinchenhao Tang.
