Test CodeFFIBR
Alias/See Also
Rapid fFN, fFN, FFN
Preferred Specimen
Vaginal swab
Instructions
Collection from Symptomatic Women: The specimen should be obtained from the posterior fornix of the vagina 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.
Collection from Asymptomatic Women: The specimen can be obtained from either the posterior fornix of the vagina or the ectocervical region of the external cervical os 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 or around the ectocervical region of the external cervical os for approximately 10 seconds to absorb the cervicovaginal secretions. Once the specimen is obtained, carefully remove the swab from the vagina or cervical os and immerse the Dacron tip in 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
1. The Rapid fFN test is to be used as an aid in assessing the risk of preterm delivery is less than or equal to 7 or 14 days from the time of cervicovaginal sample collection in pregnant women with signs and symptoms of early preterm labor, intact amniotic membranes and minimal cervical dilatation (< 3 cm), sampled between 24 weeks, 0 days and 34 weeks, 6 days gestation.
2. The Rapid fFN test is further indicated for use in conjunction with other clinical information as an aid in assessing the risk of preterm delivery in less than or equal to 34 weeks, 6 days when a cervicovaginal sample is obtained during a routine prenatal visit between 22 weeks, 0 days and 30 weeks, 6 days of gestation in women with a singleton pregnancy.
