Catalog ID FTL FIBRON Fetal Fibronectin

Important Note

Detection of fFN in cervicovaginal secretions is associated with preterm delivery in symptomatic pregnant women between 24 weeks and 34 weeks, 6 days gestation (1-6), and in asymptomatic pregnant women between 22 weeks and 30 weeks, 6 days gestation (7-10). Rapid fFN is a qualitative test for the detection of fetal fibronectin.

  1. The Rapid fFN test is to be used as an aid in assessing the risk of preterm delivery in less than or equal to 7 or 14 days from the time of cervicovaginal sample collection in pregnant women with signs and symptoms of early preterm labor, intact amniotic membranes and minimal cervical dilatation (< 3 cm), sampled between 24 weeks, 0 days and 34 weeks, 6 days gestation.
  1. The Rapid fFN test is further indicated for use in conjunction with other clinical information as an aid in assessing the risk of preterm delivery in less than or equal to 34 weeks, 6 days when a cervicovaginal sample is obtained during a routine prenatal visit between 22 weeks, 0 days and 30 weeks, 6 days of gestation in women with a singleton pregnancy.
