Secretory immunoglobulin A (S-IgA) was estimated in amniotic fluid samples by means of the single radial immunodiffusion according to Mancini. A monospecific antiserum against human secretory component was used. 163 amniotic fluid samples from normal pregnancies and risk pregnancies respectively were investigated. Within the 3rd trimenon the S-IgA content in amniotic fluid increased significantly. With respect to literature and examinations performed previously a connection between S-IgA content in amniotic fluid and fetal lung maturity seems to be possible.
