Question

Australian antigen for hepatitis b is?

• A. Hb S ag
• B. Hb E ag
• C. Hb D ag
• D. HbV Dna

Answer 1

The Correct Option is A

In the context of hepatitis B, the "Australian antigen" refers to the surface antigen of the hepatitis B virus (HBV), also known as HBsAg, where "HB" stands for hepatitis B, "s" for surface, and "Ag" for antigen. This antigen is the primary marker used for detecting active hepatitis B infection.

Antigen	Type
Hb S ag	Hepatitis B surface antigen (HBsAg)
Hb E ag	Hepatitis B e antigen (HBeAg)
Hb D ag	Not a recognized hepatitis marker
HbV Dna	HBV DNA - Represents viral genetic material

In summary, the Australian antigen for hepatitis B is correctly identified as HBsAg, making the correct answer Hb S ag.
