Hep B Titer
Determine your immunity against HBV due to vaccination or previous infection.
HBV is a viral infection that affects the liver. This test checks for the blood level of hepatitis B surface antibody (anti-HBs) to determine if a person has developed immunity against the hepatitis B virus. A positive test result indicates immunity against hepatitis B infection, either from vaccination or previous HBV infection. A negative test result indicates the absence of antibodies to Hepatitis B and no evidence of immunity.
