Epstein Barr virus capsid IgG Ab avidity [Presence] in Serum by Immunoassay

Part Description

LP145572-6 Epstein Barr virus capsid Ab.IgG avidity
Avidity testing of Epstein Barr virus (EBV) capsid IgG is performed to differeniate between a primary and past infection. When B cells switch from the IgM to the IgG isotype in vivo, the first IgG antibodies produced are of low avidity. As IgG antibodies mature, B-cells end up producing IgG antibodies of relative higher avidities or binding strengths compared to early IgG antibodies. The IgG maturation process is usually completed within a few weeks after primary EBV infection. Measurements are obtained by EIA and a ratio is calculated between a patient's urea-treated and non-urea-treated samples to define the avidity index.

Basic Attributes

Class: MICRO
Type: Laboratory
First Released: Version 2.40
Last Updated: Version 2.68
Change Reason: Property has been changed from ACnc to reflect the fact that the definition of high or low avidity is determined by a defined cut-off point (threshold); 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.
