Negative fFN Test

Bernard @ May 3, 2005, 2:43 pm -- [Week 25, Day 1]

One of the risks in twin pregnancies is that they arrive early, so starting from 22 weeks or so doctors start to monitor for signs of pre-term labor. In our last OB appointment, the doctor did a test to see if fetal fibronectin (fFN) could be detected. Fetal fibronectin is a protein that helps hold the gestational sac to the uterine wall. If the test picks up signs of this protein during the third trimester (which indicates that the sac may be coming loose) and there are other signs of labor, then we need to worry about labor starting too early. The lack of this protein in the test is a good thing.

Our doctor called us yesterday with the news from the fetal fibronectin test. It came back negative!
