Fetal Fibronectin Test

http://www.medicalook.com

FETAL FIBRONECTIN TEST DEFINITION

A fetal fibronectin test (also known as preterm labor test) involves the analysis of the fetal fibronectin, which is a protein that acts as "glue" during pregnancy. It attaches the fluid-filled membrane that cushions your baby in the uterus (the amniotic sack) to the uterus's lining. It's the test used to rule out preterm labor.

FETAL FIBRONECTIN TEST PURPOSE

The fetal fibronectin test is best used on women who are at high risk of preterm labor (premature birth). For the most part, it's not useful for women who have low preterm labor risk. A healthcare provider will be able to take steps to address preterm labor once it has been confirmed by the fetal fibronectin test.

FETAL FIBRONECTIN TEST RISKS

There's little to no risk associated with the fetal fibronectin test. It's a simple, straightforward process that poses no risk of miscarriage or other complications to a pregnant woman and her unborn child.

FETAL FIBRONECTIN TEST PREPARATION REQUIRED

No special preparations are needed in order to take this test. However, it's best that you avoid sex within a day's period (24 hours) before the test. If vaginal bleeding occurs, the test will likely be postponed. If your water (amniotic sac) breaks, the test will be canceled because delivery is inevitable.

FETAL FIBRONECTIN TEST PROCEDURE

You'll first put on a hospital gown and then lie on your back on an exam table. A speculum is then inserted into your vagina in order to enable your doctor to do a cotton swab swipe of your cervical canal. The sample will then be sent to the laboratory for examination. You may undergo a vaginal ultrasound involving a slender, wand-like device afterwards to measure the length of your cervix.

FETAL FIBRONECTIN TEST COMPLICATIONS

There are no possible risks for pregnancy complications like miscarriage when undergoing a fetal fibronectin test. All it entails is a gentle cotton swab swipe from the cervical canal and perhaps a transvaginal ultrasound.

FETAL FIBRONECTIN TEST SIDE EFFECTS

The fetal fibronectin test involves no side effects. Aside from experiencing a measure of discomfort from having a speculum placed inside your vagina, the test itself is relatively harmless.

FETAL FIBRONECTIN TEST RESULTS

The results of the fetal fibronectin test can either be negative or positive. A positive result means that fetal fibronectin is present. If you have a positive result between Weeks 24 and 34, your risk for preterm labor will increase. A negative result means that fetal fibronectin isn't present and your pregnancy will continue for another week or so.
