False positive: False-positive results can occur if a woman has recently had : 1) A pelvic exam. To reduce the risk of a false-positive result, it is important that a fetal fibronectin test be done before a manual pelvic exam.
2) Sexual intercourse.
3) Uterine contractions.
4) Bleeding from the vagina. Discuss this with your OB if you have questions

Preterm labor; fFN: Fetal fibronectin can be described as the "glue" that attaches the membranes of the amniotic sac to the side wall of the uterus. If the "glue" starts to leak out giving you a positive test, then you are at greater risk to deliver prematurely. Your risk of early labor is higher since your test is positive. Treatment options include, bed rest, steroids and close observation.
