Cervical Length Plus fFN: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Preterm Labor:
cervical length <=15mm OR cervical length 16-30mm + fFN >=50ng/ml

for delivery <35wk

in this study, results not significantly different from using fetal fibronectin alone (but saves fFN tests)
