Can HBsAg become negative after treatment?

Patients who become HBsAg negative and develop antibody to HBsAg (anti-HBs) are diagnosed as having resolved hepatitis B [3,4]. This is an uncommon phenomenon in chronic HBV infection. During stage HBV DNA may still be detectable by PCR in serum and more often in the liver.

What does HBsAg positive indicate?
