Infectious Disease
Also known as: HBsAg
If you have symptoms like dark urine, yellow skin or eyes, severe fatigue, or abdominal pain, and suspect Hepatitis B exposure, contact your doctor promptly. These could be signs of an acute infection.
This test searches for special proteins. These proteins are on the outside of the Hepatitis B virus. They are called antigens.
Your doctor orders this test to see if you have a new or long-lasting Hepatitis B infection. It also helps check people who might be at risk for this infection.
HBsAg test results are typically qualitative (positive or negative). Interpretation can depend on clinical context, and ranges may vary by lab.
