[Determination of immunoglobulins IgG, IgM and IgA in maternal serum in patients with intrauterine growth retardation].

Immunoglobulin IgG, IgM, and IgA were analysed in maternal serum of 33 patients with intrauterine growth retardation and 30 patients without hypotrophic newborns. The estimations of the immunoglobulins were carried out by means of single radial immunodiffusion according to Mancini and coworkers. There were no significant differences between both groups of patients. Therefore IgG, IgM, and IgA are no additional parameters for estimation of the placental function of the 3rd trimester of pregnancy.
