Comparison of Fetal Fibronectin (fFN) Specimen Collection Methodologies: With Speculum Versus Without Speculum

Observational study to determine whether the proposed method of fFN specimen collection without a speculum is substantially equivalent to the approved method with a speculum examination when obtained at the gestational age of ≥ 24 weeks and ≤ 34, 6 days in symptomatic women and at the gestational age of ≥ 22 weeks, 0 days and ≤ 30, 6 days in asymptomatic women. A finding of substantial equivalency would support a modification to the labeling to allow the collection of specimens for fFN determination with or without a speculum examination.
