Specimen: 

Specimen Collection Kit may be obtained from the Lab.  This kit is the only acceptable collection system available.

Specimen Collection Precautions and Warnings:

  1. Specimens for Fetal Fibroncetin should be collected prior to culture specimens. 
    Collection of vaginal specimens for culture requires aggressive collection techniques which may abrade the cervical or vaginal mucosa. 
    Cellular debris may potentially interfere with sample preparation.
  2. Specimens should be obtained prior to digital cervical examination or vaginal probe ultrasound exam as manipulation of the cervix may cause the release of fetal fibronectin.
  3. Patient specimens should not be tested if the patient has had sexual intercourse within 24 hours prior to the sampling time because semen and/or sperm may increase the possibility of the test giving a false positive result.
  4. Care must be taken not to contaminate the swab or cervicovaginal secretions with lubricants, soaps, or disinfectants. 
  5. Patient using Terazal, a vaginal cream used for yeast infection, should wait 24 hours before collecting a specimen.
  6. Rupture of membranes should be ruled out prior to specimen collection since fetal fibronectin is found in both amniotic fluid and the fetal membranes.
  7. Specimens should not be obtained from patients with suspected or known placental abruption or placenta previa.
  8. Not intended for use in patients with cancers of the reproductive tract.
  9. Not intended for use in patients with moderate or gross bleeding

Specimen Collection Instructions are included in the collection kit.

TEST NAME

FOLIC ACID RBC /  FOLATE RBC

See: FOLATE SERUM

Comment:

Recommended Alternate testing: Folate Serum

True folate deficiency in the current era of FDA-mandated folic acid supplementation is exceedingly rare. There is no evidence to support routine ordering of RBC or serum folate, but serum folate concentrations provide equvalent clinical information to RBC folate in the assessment and diagnosis of folate deficiency. Based on these statistics, and because serum folate provides equivocal results to RBC folate in almost all clinical scenarios, routine ordering of RBC folate is no longer warranted. Furthermore, investigation of megaloblastic anermia should preferentially be initiated with vitamin B12 testing instead of folate due to the low incidence of modern folate deficiency. In the absence of B12 deficiency, it is more cost effective to simply supplement with folic acid rather than routinely test and monitor a patient's folate status, similar to other nutritional deficiencies such as vitamin D.
