Fetal Fibronectin Test

The Fetal Fibronectin (fFN) test is a diagnostic tool used during pregnancy to assess the risk of preterm birth. It measures the presence of a protein called fetal fibronectin in the cervix or vaginal secretions, helping healthcare providers determine if a woman is at an increased risk of delivering her baby prematurely.

The fFN test is a non-invasive procedure. A swab is gently inserted into the vagina and cervix to collect a sample of cervical or vaginal secretions. This swab is then sent to a laboratory for analysis, where the presence of fetal fibronectin is detected. The entire process is relatively quick and usually painless.

The fFN test has a higher negative predictive value, meaning a negative result is more reliable than a positive one. However, it is not 100% accurate, and false-positive results can occur. It should be used in conjunction with other clinical assessments to make informed decisions about patient care.

A high level of fetal fibronectin can indicate an increased risk of preterm birth within the next one to two weeks. However, it is important to remember that this is not a guarantee, and healthcare providers will use this information to take appropriate actions to manage the pregnancy.
