Fetal fibronectin is elevated in cervicovaginal secretions during the first 24 weeks of pregnancy but is diminished between 24 and 34 weeks in normal pregnancies.The Fetal fibronectin (fFN) Rapid Test Cassette (vaginal secretion) is a visually interpreted, qualitative immunochromatographic test device for the detection of fFN in cervicovaginal secretions to be used as an aid to assess the risk of pre-term delivery during pregnancy. The test is intended for professional use to help diagnose the rupture of fetal membranes (ROM) in pregnant women.
