Correlation between specific IgM levels and percentage IgG-class antibody avidity to Toxoplasma gondii.
Toxoplasmosis is an usually asymptomatic worldwide disseminated infection. In its congenital presentation it may lead to abortion or fetal malformations. Antenatal evaluation is considered of paramount importance to identify seronegative women and allow for prophylaxis. Recent improvements in sensitivity of IgM tests has made IgM detection an extremely protracted acute phase marker, and IgG avi...
متن کاملEvaluation of the new LIAISON(®) CMV IgG, IgM and IgG Avidity II assays.
BACKGROUND The diagnosis of CMV infection is challenging and the quality of serological laboratory testing is critical, especially in pregnancy and in the determination of transplant recipients and donors serostatus. OBJECTIVES Evaluate the performances of the new LIAISON(®) CMV II line: LIAISON(®) CMV IgG II, LIAISON(®) CMV IgM II and LIAISON(®) CMV IgG Avidity II in comparison with the rout...
متن کاملAppraisal of Prenatal Anti-toxoplasma Gondii (igg+igm)- Iha/igm-elisa Screening in Single Samples via Igg Avidity Test.
Congenital toxoplasmosis is associated with important morbidity and mortality. Since vertical transmission of Toxoplasma gondii can occur in acute cases, antenatal screening for recent infections is vital. Accurate determination of acute toxoplasmosis requires a combination of immunoassays, usually not routinely applied for screening purposes. This study evaluated the anti-T. gondii (IgG+IgM)/I...

since the incidence of symptomatic congenital cytomegalovirus infection is low (~0.05%) and risk factors are not well defined, it is difficult to develop strategies for prevention. the aim of this study was to recognise the utility of specific immunoglobulin g avidity analysis for distinguishing primary infection from past/recurrent infection. sera from 50 women with cytomegalovirus specific im...
