[Serological monitoring and prevention of toxoplasmosis during pregnancy].

Serological monitoring and prevention of toxoplasmosis during pregnancy. Determination of the serological status against toxoplasmosis is mandatory in France during pregnancy. Recently, the national social welfare system decided to include new exams (IgG avidity and western-blot) useful to assess the serological status and to date the infection with a better accuracy. The role of the attending doctor is essential, particularly at the beginning of pregnancy and after delivery. We summarize here key points which must be known by a general practitioner to understand serological results and take care of his patients.
