There are several different tests for hepatitis B depending on what information you want to find out. These include surface antigen testing to look for an active virus and antibody testing to look for previous exposure and immunity.
Symptoms of Hepatitis B
Hepatitis B is a virus that affects the liver. Symptoms include low-grade fever, nausea and vomiting, and joint pain. There may also be signs of a liver infection, such as jaundice (yellowish colouring of the skin and eyes), pale faeces, itchy skin, or abdominal pain.
Hepatitis B is transmitted predominantly through unprotected sexual contact, or through sharing infected needles.
Treatment for Hepatitis B
There is no treatment for hepatitis B, but it usually clears up within three months – it lasts for six months in a fraction of cases, often without symptoms (chronic hepatitis B), but can cause cirrhosis (scarring of the liver).
