Fetal Fibronectin

Fetal fibronectin (fFN) is a fibronectin protein produced by fetal cells. It acts as a "glue" during pregnancy, attaching the amniotic sac to the lining of the uterus.

Fetal fibronectin is often present in vaginal discharge before week 22 of pregnancy. Fetal fibronectin also begins to break down and can be detected in vaginal discharge toward the end of pregnancy.

Studies have shown an association between the presence of fetal fibronectin and preterm birth.
