Term Description

All of the major laboratories whose web sites we explored perform a confirmatory test to verify positive results on their routine HBS Ag EIA test. Some indicate that the confirmatory test requires and an extra charge, some do not. We believe that at present (2011) the confirmatory test is usually a neutralization test. But only one lab that we reviewed specified the method as such. This term covers all confirmatory methods and will not require changing if/when confirmatory methods change.

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 scale has been changed from ACnc to reflect new model for ordinal terms; 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.
