[Value of IgA detection in the diagnosis of toxoplasmosis]
1Laboratoire de Microbiologie, Universitaire, Côte de Nacre, CAEN, France.
The detection of IgA in serum by immunocapture agglutination assay is easy to perform in routine. It represents a valuable element for the diagnosis of toxoplasmosis. The presence of IgA, even more than that of IgM, evokes a recent infection. However, caution must be taken in using the results to date back the infection since kinetics of IgA production, like other immunoglobulins, may depend on individual variations.
