75407-7Hepatitis B virus e Ab [Presence] in Serum, Plasma or Blood by Rapid immunoassayActive

Term Description

Rapid test for hepatitis B envelope antibody (HBeAb) used as a screen for Hepatitis B, or to monitor the early course of disease, as the appearance of HBeAb marks the transition from high levels of virus replication and infectivity to low levels of replication and infectivity. Available in test strip and cassette formats from manufacturers in various countries including the US and China, the test can be used to evaluate the presence of HBeAb in blood and blood products intended for transfusions, and to detect ongoing or previous hepatitis B viral infection. (As of 8/25/2014, no HBeAb rapid test kits are approved for use in the United States.) This term was created for, but not limited in use to, the MEDINOSTICS International HBeAb Rapid Screen Test kit which is a colloidal gold enhanced immunoassay for the detection of anti-HBe in human serum, plasma or whole blood. It provides a visual, qualitative result and can be done in approximately 15 minutes.

Part Description

LP16709-5   Hepatitis B virus little e
The hepatitis B surface antigen (HBsAg) is most frequently used to screen for the presence of a Hepatitis B virus infection. It is the first detectable viral antigen to appear. Shortly after the appearance of the HBsAg, another antigen called hepatitis B e antigen (HBeAg) will appear. Traditionally, the presence of HBeAg in a patient's serum is associated with much higher rates of viral replication and enhanced infectivity; however, variants of the hepatitis B virus do not produce the 'e' antigen, so this rule does not always hold true. During the natural course of an infection, the HBeAg may be cleared, and antibodies to the 'e' antigen (anti-HBe) will arise immediately afterwards. This conversion is usually associated with a dramatic decline in viral replication. 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.
