Hepatitis B Serology
Within scope of accreditation
5-10% of healthy adults will not recover from acute hepatitis B infection and will develop chronic Hepatitis B infection. This percentage increases the younger the patient. Determining the Hepatitis B status using all markers such as HBeAg will ensure the patient can be treated with antiviral drugs and monitored for response and/or disease progression. HBsAb is used to indicate immunity post immunisation.
