|
|
|
| Specimen: |
|
Cervicovaginal secretion
|
|
|
|
|
|
|
| Patient Preparation: |

|
|
|
|
|
|
|
| Collection Instructions: |
|
1. Obtain prior to digital cervical examination or vaginal
probe ultrasound examination as manipulation of the
cervix may cause release of fetal fibronectin.
2. Do not use lubricants, soaps, or disinfectant (e.g.
K-YŽ Jelly lubricant, BetadineŽ disinfectant,
hexacholorophene) on speculum or cervicovaginal
secretions as they may interfere with test.
