[The importance of fibronectin in amniotic fluid in anticipation of premature labor].

We analysed 86 pregnant women where we estimated the fibronectin level in specimens of amniotic fluid. During carrying out the experiment we noted that fibronectin is present in amniotic fluid and can be identified in a quantity mode. We have proved dependence between fibronectin level in amniotic fluid and the period of time from collecting the sample, up to the delivery. Fibronectin level in amniotic fluid doesn't depend on pregnancy duration, preterm rupture of amniotic membranes.
