[Gel fractionation of immunoglobulins in the detection of specific antitoxoplasma IgM. Evaluation of a 1-year study].

Toxoplasmosis seroconversion is diagnosed on the presence of fluorescent antibodies. IgG level kinetics and presence of IgM at the Remington test are usually the points taken in consideration. But the Remington test can be false positive, or inadequate. The authors report their experience of gel filtration of sera in toxoplasmosis, and discuss the help that this method can be establishing diagnosis in the case of a positive Remington test.
