Viral Hepatitis Immunity Profile (HAV and HBV)

CPT: 86704; 86706; 86708

Synonyms

  • Hepatitis
  • Hepatitis A
  • Hepatitis B

Test Includes

Hepatitis A Virus (HAV) Antibody, Total; Hepatitis B Surface Antibody (anti-HBs); and Hepatitis B c Antibody (anti-HBc), Total


Special Instructions

This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.

Test Details


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.


Limitations

The assays in this panel have not been FDA cleared or approved for the screening of blood or plasma donors. Assay performance characteristics have not been established for immunocompromised or immunosuppressed patients, coed blood, or patients less than 2 years of age.


Methodology

Immunochemiluminometric assay (ICMA)
