97152-3
LaboratoryHBc+HBe+p22cr Ag [Units/volume] in Serum or Plasma by Immunoassay
Definition
Quantitative detection of Hepatitis B virus (HBV) core-related antigens, including HB core, pre-core (also known as p22cr) and envelop antigens, in serum or plasma by immunoassay methods, such as chemiluminescent enzyme immunoassay (CLEIA). This test does not distinguish between the three antigens. Testing is performed for the diagnosis of chronic and acute hepatitis B and to monitor treatment. Studies have shown that HBVcr Ag levels in serum correlate with serum HBV DNA and intrahepatic covalently closed circular DNA (cccDNA).[PMID: 31075974]
