Preferred Specimen
Swab
Instructions
The specimen should be obtained from the posterior fornix of the vagina or the ectocervical region of the external cervical os (asymptomatic women only) during a sterile speculum examination. The Dacron swab provided in the Specimen Collection Kit should be inserted into the vagina and lightly rotated across the posterior fornix for approximately 10 seconds to absorb the cervicovaginal secretions.
Once the specimen is obtained, place it into the tube of buffer provided with the Specimen Collection Kit. Break the shaft (at the score) even with the top of the tube. Align the shaft with the hole inside the tube cap and push down tightly over the shaft, sealing the tube.

Clinical Significance
Fetal Fibronectin is a protein that performs two roles during pregnancy. It is produced by the placenta and acts as the glue that attaches the placenta to the uterine wall. In late pregnancy, it acts as a lubricant, aiding in the passage of the newborn through the vaginal canal. Amniotic fluid contains Fetal Fibronectin and when the membranes leak, fFN can be detected in a cervicovaginal collection. This can be used as a predictor of preterm delivery, defined as less than 37 weeks gestation.
