DEEPBLUE Fetal fibronectin (fFN) Test Kit (Colloidal Gold)

Detection principle

Fetal fibronectin (fFN)is a component of the extracellular matrix of the uterine chorionie villus, mainly produced by trophoblast cells, and exists between the chorionic villus and the metaphase as a glycoprotein that acts as a linking and adhesion protein to the chorionic villus and metaphase.

1.Normal pregnant women have very low levels of fFN <50 ng/mL in cervicovaginal secretions at 22-35 weeks of gestation.

2.When the level of fFN is >50 ng/mL, it indicates the possibility of preterm labour.
