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
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)
Associated Diagnoses:
67% sensitive, 81% specific
86% sensitive, 90% specific
