What is Australia antigen HBsAg positive?
HBsAg (also known as the Australia antigen) is the surface antigen of the hepatitis B virus (HBV). Its presence in blood indicates current hepatitis B infection.
What does Australian antigen mean?
The Australia-antigen (HBSAG) is a simple detectable marker of an infection with hepatitis B virus. By demonstration of HBSAG an acute hepatitis B can be differentiated from other forms. Likewise the detection of HBSAG in chronic active hepatitis can differentiate the viral induced type from the autoimmune type.
What is Au Ag test?
The Australia antigen is a specific antigen used to diagnose patients with the hepatitis B virus. It got its name because it was first found in an Australian aborigine, but now we know it appears in anyone with hepatitis B. To understand this antigen’s role, it’s useful to first know more about hepatitis B.
Which antigen is known as an Australian antigen?
Australia antigen [Au(1)], a particle associated with viral hepatitis, was isolated from the plasma of a patient with chronic anicteric hepatitis and leukemia who had received radioactive phosphorus.
What is the HBsAg meaning?
Abstract. Following infection with hepatitis B virus (HBV), hepatitis B surface antigen (HBsAg) is detectable in the serum before liver function tests become abnormal and before development of clinical features of hepatitis; HBsAg tests usually become negative shortly after illness subsides.
What does it mean if HBsAg is negative?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months.
When does HBsAg become positive?
HBsAg will be detected in an infected person’s blood an average of 4 weeks (range: 1–9 weeks) after exposure to the virus.
What is the Australia antigen?
An antigen is a piece of a virus that can be found in the blood and often causes the immune system to respond to an infection. The Australia antigen is a specific antigen used to diagnose patients with the hepatitis B virus. It got its name because it was first found in an Australian aborigine, but now we know it appears in anyone with hepatitis B.
What is HBsAg (Australia antigen)?
HBsAg (also known as the Australia antigen) is the surface antigen of the hepatitis B virus (HBV). It indicates current hepatitis B infection. The viral envelope of an enveloped virus has different surface proteins from the rest of the virus which act as antigens.

What is Blumberg antigen?
It is commonly referred to as the Australia Antigen. This is because it was first isolated by the American research physician and Nobel Prize winner Baruch S. Blumberg in the serum of an Australian Aboriginal person. It was discovered to be part of the virus that caused serum hepatitis by virologist Alfred Prince in 1968.
