Approach to HBsAg-Positive Patients
This answer is correct. The initial laboratory evaluation of a positive HBsAg includes a complete hepatitis B serologic evaluation, including IgM anti-HBc, HBeAg, and hepatitis B e antibody (anti-HBe). In addition, studies should be performed to measure serum HBV DNA level and biochemical markers related to hepatic inflammation and function. These tests are essential to accurately characterize the patient’s HBV infection.
