The difference between major triple yang and minor triple yang are two different stages after hepatitis B virus infection is as follows: 1. Major triple yang is positive for hepatitis B E antigen and negative for hepatitis B E antibody in addition to positive for hepatitis B surface antigen and hepatitis B core antibody. And the small three yang is in addition to hepatitis B surface antigen and hepatitis B core antibody positive, hepatitis B E antibody positive, hepatitis B E antigen negative. 2, the large three yang viral amount is high and infectious, the small three yang viral amount is low. The actual fact is that you can’t determine the severity of the patient’s condition and the level of contagiousness simply by whether hepatitis B is a major or minor triplet, but also by checking the liver function, hepatitis B virus quantification, liver, gallbladder and spleen ultrasound, etc. Once you find a positive hepatitis B surface antigen, whether it’s a major or minor triplet, you should go to the hospital for further examination and ask a specialist for treatment.
