What does a hepatitis B surface antigen level of 28.6 ng/ml mean?

　　An HBsAg level of 28.6 ng/ml indicates infection with the hepatitis B virus, and the specific analysis is as follows:

　　An HBsAg level of 28.6 ng/ml indicates hepatitis B virus infection, as this antigen is the earliest marker to appear after HBV infection. After the hepatitis B virus invades liver cells, it replicates within the cells, and antigens formed from its surface components are released into the bloodstream. Under normal circumstances, such antigens cannot be detected in the blood; therefore, any value exceeding the reference range indicates the presence of the virus in the body and potential viral replication. Further evaluation combining other indicators is needed to determine the stage of infection and severity of the disease.

　　In daily life, maintain a regular schedule and avoid staying up late to allow sufficient liver recovery. Reduce intake of high-fat and high-sugar foods, and consume more fresh fruits, vegetables, and high-quality protein. Strictly abstain from alcohol, and do not take medications or supplements that may harm the liver without medical guidance. Regularly recheck relevant indicators to monitor viral activity and liver function. Practice good personal hygiene, and avoid sharing personal items such as toothbrushes and razors to reduce the risk of transmitting the virus to others. Maintain a positive mindset and actively cooperate with follow-up diagnosis and treatment.
