Fetal Fibronectin (fFN) Predicts Preterm Birth Risk

fFN acts as an adhesive glycoprotein at the maternal-fetal interface that bonds maternal membranes to fetal membranes.

It is a biomarker for preterm delivery and is highly associated with the risk of preterm delivery when present in cervicovaginal secretions.

fFN testing is the only named biomarker test recommended by the NICE clinical guidelines for the risk assessment of preterm labour & birth.3

More information and less guesswork, to better predict the likelihood of preterm birth.

Quantitative fFN testing detects the concentration levels of fFN that are present, giving you the data you need to determine a woman’s risk of preterm delivery.2
