What is the prognosis of HBsAg positive or negative?
The titre of HBsAg in the serum rapidly declines during the first 6 weeks after the onset of illness; it is even possible for a patient with acute hepatitis B to have a negative serum HBsAg test result after only a few days of jaundice due to the rapid clearing of the antigen from the blood.
