Hepatitis B virus surface Ag [Presence] in Serum, Plasma or Blood by Rapid immunoassay

Active

Term Description

Hepatitis B surface antigen (HBsAg) rapid tests are available in test strip and cassette formats from manufacturers in various countries including the US, Singapore, and China. (As of 8/25/2014, no HBsAg rapid test kits are approved for use in the United States). Hepatitis B surface antigen (HBsAg) rapid tests are intended to be used for screening patients for hepatitis B infection and for screening blood donors and blood products. HBsAg is the first serologic marker to appear in the blood of patients infected with hepatitis B, prior to the onset of symptoms. HBsAg can be detected 2-4 weeks in advance of alanine aminotransferase (ALT) liver enzyme levels becoming increased, and 3-5 weeks prior to symptoms. This makes HBsAg rapid tests particularly useful for screening. Follow-up and supplementary testing of any positive samples with other analytical methods (e.g. ELISA, WB)are required however, and negative results do not exclude Hepatitis B virus (HBV) exposure or infection. This term was created for, but not limited in use to, the OneStep HBsAG RapiCard InstaTest kit which uses a chromatographic lateral flow device technique on whole blood, serum, or plasma. Test cassette must be at room temperature prior to testing and then results can be read within 15 minutes.

Part Description

LP14820-2 Hepatitis B virus surface
The hepatitis B surface antigen (HBsAg) is most frequently used to screen for the presence of this infection. It is the first detectable viral antigen to appear during infection. However, early in an infection, this antigen may not be present and it may be undetectable later in the infection as it is being cleared by the host. The infectious virion contains an inner "core particle" enclosing viral genome. The icosahedral core particle is made of 180 or 240 copies of core protein, alternatively known as hepatitis B core antigen, or HBcAg. During this 'window' in which the host remains infected but is successfully clearing the virus, IgM antibodies to the hepatitis B core antigen (anti-HBc IgM) may be the only serological evidence of disease. Therefore most hepatitis B diagnostic panels contain HBsAg and total anti-HBc(both IgM and IgG). Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

Change Reason: The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
