fFN (Fetal Fibronectin) Test

Fetal Fibronectin Testing

A fetal fibronectin test is a safe, reliable way to find out if your body is getting ready to deliver your baby. It's a simple, non-invasive test that can be given in your doctor's office, and is the most powerful predictor of preterm birth <32 weeks.1

IN THIS SECTION

Fetal fibronectin (fFN) is a "glue-like" protein your body makes to hold your baby in your womb. When your body is getting ready to give birth, this glue breaks down and leaks out of the uterus. Measuring the level of fetal fibronectin through a simple test can show if your body is getting ready to give birth.

From weeks 22 to 35 of pregnancy, fetal fibronectin should be almost undetectable. This test detects the presence of fetal fibronectin, which can indicate if your body is getting ready for a premature delivery.

If you are at risk for preterm birth, or are having symptoms, your doctor may recommend this test. Testing for the presence of fFN is a way for you to be involved in your pregnancy and your baby's health. The more you know, the more you can prepare.

A fetal fibronectin test is a safe, reliable, non-invasive test (similar to a Pap test) that can help your doctor determine if your body may be getting ready for delivery, even before you feel any of the symptoms.

Several doctors who use fFN testing explain the benefits of the test for pregnant women in their care.
