Introduction 

Fetal fibronectin (fFN) is a "glue-like" protein that bonds your developing baby to your uterus. Fetal fibronectin is detectable in vaginal secretions in the very beginning of pregnancy, when this bond is first forming, and then again at the end of pregnancy, when your body is getting ready to deliver your baby. fFN is a special protein that literally holds your baby in place in the womb. After the 35th week of pregnancy, it begins to break down naturally, and is detectable. If your body is getting ready to give birth prematurely, fFN may be detected before week 35. From weeks 22 to 35 in your pregnancy, there should be very little fFN detectable. FN can often be detected before other symptoms of preterm labor, such as contractions and changes in cervical length. Doctors may use a combination of signs and symptoms when deciding the best course of action to take in relation to your pregnancy.

Intend to use

The fetal fibronectin (fFN) rapid test (vaginal secretion) is a visually interpreted, qualitative immunochromatographic test device for detection of fFN in vaginal secretions during pregnancy, which is a special protein that literally holds your baby in place in the womb. The test is intended for professional use to help diagnose the rupture of fetal membranes (ROM) in pregnant women.

Operating  Steps
Premature delivery diagnostic fetal fibronectin (fFN) rapid test kit .
​​​​​​​Bring tests, specimens, buffer and/or controls to room temperature (15-30°C) before use.
1) Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. To obtain a best result, the assay should be performed within one hour.
2) Add the extracted buffer into the sample well. As the test begins to work, you will see color move across the membrane.
3) Wait for the colored band to appear. The result should be read at 10 minutes. Do  not interpret the result after 20 minutes.
