Fetal fibronectin is elevated in cervicovaginal secretions during the first 24 weeks of pregnancy but is diminished between 24 and 34 weeks in normal pregnancies.The Fetal fibronectin (fFN) Rapid Test Cassette (vaginal secretion) is a visually interpreted, qualitative immunochromatographic test device for the detection of fFN in cervicovaginal secretions to be used as an aid to assess the risk of pre-term delivery during pregnancy. The test is intended for professional use to help diagnose the rupture of fetal membranes (ROM) in pregnant women.
1.Bring tests, specimens, buffer and/or controls to room temperature (15-30°C) before use.
2.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.
3.Add 2 drops (80μl) of the extracted buffer into the sample well. As the test begins to work, you will see color move across the membrane.
4.Wait for the colored band to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
