Clinical Significance
Fetal fibronectin is a protein that performs two roles during pregnancy. It is produced by the placenta and acts as the glue that attaches the placenta to the uterine wall.ÿIn late pregnancy, it acts as a lubricant, aiding in the passage of the newborn through the vaginal canal.ÿAmniotic fluid contains fetal fibronectin and when the membranes leak, fetal fibronectinÿcan be detected in a cervicovaginal collection.ÿThis can be used as a predictor of pre-term delivery, defined as less than 37 weeks gestation.
