A semi-quantitative test for fetal fibronectin is conducted on cervicovaginal secretions to assess the risk of preterm labor. Fetal fibronectin (fFN) is a glycoprotein that acts as a biological adhesive, anchoring the fetal sac to the uterine lining during pregnancy. This protein is typically found in cervicovaginal secretions during the first 22 weeks of gestation, serving as an indicator of a healthy pregnancy. However, after this period, fetal fibronectin is generally absent until one to three weeks prior to labor onset. The presence of detectable levels of fetal fibronectin in women between 24 and 34 weeks of gestation, particularly when accompanied by symptoms indicative of preterm labor, suggests an elevated risk for preterm delivery. The test involves the collection of cervicovaginal secretions using a cotton swab, which are then analyzed to determine the presence or absence of fetal fibronectin, providing valuable information for managing pregnancy and potential preterm labor risks.

The fetal fibronectin test is indicated for the following conditions:
The procedure for conducting the fetal fibronectin test involves several key steps to ensure accurate results. First, a healthcare provider collects cervicovaginal secretions using a sterile cotton swab. This swab is gently inserted into the vagina to obtain a sample from the cervix, ensuring that the collection is done carefully to avoid any contamination. Once the sample is collected, it is placed in a designated container for testing. The sample is then analyzed in a laboratory setting, where the presence or absence of fetal fibronectin is determined through semi-quantitative testing methods. The results of this test provide critical information regarding the risk of preterm delivery, guiding further clinical management and decision-making for the patient.
After the fetal fibronectin test is performed, patients may be advised to continue monitoring for any signs of preterm labor. Depending on the results of the test, healthcare providers may recommend additional follow-up appointments or interventions to manage the pregnancy effectively. If fetal fibronectin is detected, further evaluation and potential treatment options may be discussed to mitigate the risk of preterm delivery. Patients should also be informed about the importance of reporting any new symptoms or changes in their condition to their healthcare provider promptly.
