How can the Rapid fFN® test help?


A fetal fibronectin test is one of the most powerful predictors of preterm birth.1 It is a simple non-invasive test that can be done in the hospital or in the doctor’s office, similar to a pap test.

The vast majority of patients will receive a negative Rapid fFN® test result, meaning they have less than a 1% chance of delivering in the next 2 weeks, which can help avoid unnecessary interventions.2 A positive Rapid fFN® result indicates a higher risk of a preterm delivery and helps healthcare providers decide which interventions are appropriate.


Preterm birth is the most common cause of health problems in newborns today.3


1 in 10 babies born in the United States are born premature.4
It’s important to know the signs and symptoms of preterm labor.


How does fetal fibronectin indicate risk of preterm birth?


fFN is a “glue-like” protein that helps bond your baby to the uterus. If fFN is detectable in vaginal discharge during weeks 22–35 gestation, it means that the protein is “leaking,” which can be a sign that your body is getting ready to deliver early.2
