Why Fetal Fibronectin Matters


Why Fetal Fibronectin Matters

Know the numbers to calculate a plan…


When a patient is experiencing symptoms of preterm labour, you need to determine if her risk of preterm birth is real or perhaps quite low.¹


Quantitative fetal fibronectin testing (Rapid fFN® Test) detects concentration levels of the fFN protein to reliably indicate whether a woman is likely to give birth prematurely.²

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


Maternal-fetal Interface

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. ² ³


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