- Patient Preparation
- Specimens for fetal fibronectin testing should be collected prior to collection of culture specimens. Specimens should be obtained prior to digital cervical examination or vaginal probe, ultrasound examination as manipulation of the cervix may cause the release of fetal fibronectin.
Testing should not be performed if the patient has had sexual intercourse within 24 hours prior to the sampling time because semen present may increase the possibility of a false positive result.
