Fetal fibronectin as predictor of preterm delivery in women with symptoms of preterm labor
Metadata[+] Show full item record
In pregnant patients with preterm contractions, fetal fibronectin (FFN) has a high negative predictive value (>99%) and a low positive predictive value for delivery in the 7 to 14 days after the test. In clinical practice, negative FFN results in women with symptoms of preterm labor are associated with lower admission rates and decreased cost without adversely effecting neonatal outcomes.
