Doctor's answer:
HBSAG and HBCAB positive indicate a small positive for hepatitis B, which means that in the five-item hepatitis B test, the first and fifth items show positivity, i.e., hepatitis B surface antigen is positive and hepatitis B core antibody is positive. The transition from a large positive to a small positive for hepatitis B does not hold significant diagnostic importance for confirming the condition of the disease. The patient still needs to undergo tests for HBVDNA, liver function, and ultrasound. Based on the results of the HBVDNA test, it can be inferred how hepatitis B patients with a small positive have developed viral mutation. If the viral mutation leads to the transition from a large positive to a small positive for hepatitis B, prompt treatment is necessary, otherwise the condition may continue to worsen. If there is no viral mutation after the transition from a large positive to a small positive for hepatitis B, and the liver function and ultrasound results are normal, it indicates that the condition is improving.
