The specimen must be obtained prior to digital cervical exam, vaginal probe ultrasound exam, or collection of swabs for a culture, as manipulation of the cervix may cause release of fFN. The test should not be used in the following cases: *Placenta previa or abruption *Moderate or gross vaginal bleeding *Ruptured membrane *Advanced cervical dilation (>3cm) *Sexual intercourse in preceding 24 hours (20-50% chance of false positive) Specimen Collection: Specimen collection kits with instructions are provided by the laboratory. Take care not to contaminate with lubricants, soaps or disinfectants. *The specimen must be obtained prior to digital cervical examination, vaginal probe ultrasound examination, or collection of swabs for culture, as manipulation of the cervix may cause release of fFN. *Symptomatic Women: During a sterile speculum examination, lightly rotate the supplied swab across the posterior fornix for approximately 10 seconds to absorb cervicovaginal secretions. *Asymptomatic Women: During a sterile speculum examination, lightly rotate the supplied swab across the posterior fornix or the ectocervical region of the external cervical os for approximately 10 secondto absorb cervicovaginal secretions. *Place swab in transport tube. Break the shaft (at the score). *Align shaft with tube cap and push down tightly sealing the tube. *Transport the specimens to the lab for testing at 2 to 8C (Refrigerate)
