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.
