Diagnostic Kit Fetal Fibronectin (fFN) / Vaginal Secretion Test Kit

Principle:

Fetal Fibronectin Test kit has been pre-coated with an antibody specific to fFN.Standards or samples are added to the stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)- conjugated antibody specific for fFN is added to each stripplate well and incubated.Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain fFN and HRP conjugated fFN antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of fFN. You can calculate the concentration of fFN in the samples by comparing the OD of the samples to the standard curve.

NOTE: Premature delivery is a disease with characteristics of pregnancy interruption happened between 28 weeks and 37 weeks. Premature delivery is major reason of nongenetic death and disability of most perinatal infant. No matter how the test results, it is recommended to consult your physician.
