Fetal Fibronectin (fFN)
Curious!! Has anyone else had to take this test? I'll be 30 weeks Wednesday and due November 2nd (we found out at my 28 week U/S) and My cirvics is shortening (thinning out) so now I have to take this test every two weeks to determine if my body is preparing for early delivery.

"When lab technicians analyze your sample, they measure the amount of fetal fibronectin, a protein produced by the fetal membranes. This protein serves as the "glue" that attaches the fetal sac to the uterine lining. It's normally found in increased amounts in your vagina during the first half of pregnancy and again late in pregnancy as you near labor. But if fFN leaks from the uterus and more than a small amount shows up in the vagina too early (between 22 and 34 weeks), it may mean that the glue is disintegrating ahead of schedule because of contractions or an injury to the membranes.
If this happens, your risk of going into labor and giving birth prematurely is significantly higher. More important, if no fetal fibronectin is found in your sample, it means your risk of giving birth in the next two weeks is very small. You should expect to see test results within a day or two, or within several hours if you're taking the rapid version of the test."
