Vaginal fetal fibronectin
Fetal fibronectin (fFN) is a fibronectin protein produced by fetal cells. It is found at the interface Fetal fibronectin "leaks" into the vagina if a preterm delivery is likely to occur and can be measured in a screening test. Testing will produce a. Fetal fibronectin is a protein that's believed to help keep the amniotic sac Intercourse and vaginal bleeding can affect the test results, too. Explains how the fetal fibronectin (fFN) test is used, when a fFN test is A fetal fibronectin test detects fFN in vaginal fluid to help predict the. Fetal fibronectin is largely confined to this junction and is thought to help "glue" or maintain the integrity of the boundary between the amniotic sac and the lining of the uterus. A fetal fibronectin test detects fFN in vaginal fluid to help predict the short-term risk of premature delivery. OBJECTIVE: To assess the accuracy of vaginal fetal fibronectin sampling without use of a sterile speculum examination as a screening test for predicting spontaneous preterm birth. RESULTS: A total of 1, fetal fibronectin tests from pregnancies were performed via the “blind” sampling. Mar 15, · Eligible women who presented at 24–34 weeks of gestation with threatened PTL had their cervicovaginal secretions sequentially sampled for fetal fibronectin (fFN) using two types of swabbing techniques. The first swab was a blind vaginal swab collected without the aid of speculum, while the second one was a routine cervicovaginal swab.
