Introduction
Hepatitis B surface antigen refers to the surface antigen of the hepatitis B virus. Under normal circumstances, a negative result for hepatitis B surface antigen is considered normal. The hepatitis B surface antigen is a glycoprotein on the surface of the hepatitis B virus; it does not represent the complete hepatitis B virus, but rather the outer coat of the virus. Although the hepatitis B surface antigen itself is not infectious, it is antigenic. The normal reference range is 0–1 COI.
HBsAg refers to hepatitis B surface antigen. Under normal circumstances, a negative result for hepatitis B surface antigen is considered normal. The specific analysis is as follows:
Hepatitis B surface antigen is a glycoprotein on the surface of the hepatitis B virus. It does not refer to the complete hepatitis B virus, but rather to the outer shell of the virus. Although the hepatitis B surface antigen itself is not infectious, it is antigenic. The normal reference range is 0–1 COI. A negative test result for hepatitis B surface antigen usually indicates that there is no infection with the hepatitis B virus, or that the virus has been cleared after treatment. This is a normal condition and typically does not require special treatment.
It should be noted that factors such as improper laboratory procedures or inadequate specimen collection may affect the accuracy of the hepatitis B surface antigen test results. If there are concerns about potential errors in the test result, timely retesting is recommended.
