General Information About the Test
Test Process and Preparation
A "Positive (Reactive)" HBsAg result indicates that the person is infected with the Hepatitis B virus and can transmit this virus to others through blood or sexual contact. They should immediately be placed under follow-up by an infectious diseases specialist.
No. In a person who has been successfully vaccinated against Hepatitis B and acquired immunity, HBsAg will be "Negative", while Anti-HBs, the protective antibody, will be "Positive".
Because this is an antigen (virus particle) detection test, it is not affected by nutritional status. It can be performed with a tube of blood drawn from the arm at any time and regardless of being full or fasting.
