Viral Hepatitis Immunity Profile (HAV and HBV)
Also known as: Hepatitis, Hepatitis A, Hepatitis B
Use
To access patients for immunity to Hepatitis A Virus (HAV) and Hepatitis B Virus (HBV). Detectable total anti-HAV antibody indicates immunity to HAV infection. Although usually not sensitive enough to detect the low level of protective antibody after vaccination, anti-HAV tests also might be positive after hepatitis A vaccination. The detection of anti-HBs antibodies in the absence of anti-HBc antibodies indicates immunity to HBV infection due to vaccination. The detection of both anti-HBs and anti-HBc antibodies indicates immunity due to natural infection.
Special Instructions
This test may show interference if the sample is collected from a person consuming a supplement with a high dose of biotin. Patients should stop biotin consumption at least 72 hours before sample collection.
