Part Descriptions

LP14414-4 Hepatitis B virus core
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.

LP38323-9 Hepatitis B virus core Ab
Hepatitis B core antibody (anti-HBc) appears at the onset of symptoms in acute hepatitis B and persists for life. Presence of anti-HBc indicates previous or ongoing infection with
hepatitis B virus in an undeﬁned time frame. Source: Regenstrief LOINC, Interpretation of Hepatitis B Serologic Test Results

Basic Attributes

Class: MICRO
Type: Laboratory
First Released: Version 1.0m
Last Updated: Version 2.69 (MIN)
Change Reason: 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.
Order vs. Observation: Both
