Specimen Collection Criteria
Collect: Infants first stool (meconium).
Note: For maximum sensitivity, collect all meconium from first passage until transitional milk stool. For average sensitivity, collect four (4.0) grams. The labaratory will analyze amounts under four grams, but that sensitivity will be lost.
Physician Office/Drawsite Specimen Preparation
Maintain specimen refrigerated (2-8°C or 36-46°F) prior to transport.
Preparation for Courier Transport
Transport: 4.0 g meconium, refrigerated (2-8°C or 36-46°F). (Min: 2.0 g)
- Yellow stool specimens may be rejected.
- Specimens not collected and processed as indicated.
Specimen Stability for Testing:
Room Temperature (20-26°C or 68-78.8°F): 7 days
Refrigerated (2-8°C or 36-46°F): 3 months
Frozen (-20°C/-4°F or below): 1 year
Specimen Storage in Department Prior to Disposal:
Specimen retention time is determined by the policy of the reference laboratory. Contact the Sendout Laboratory with any questions.
Sent to ARUP Laboratories, Salt Lake City, UT.
Sunday - Saturday.
Results available in 2-5 days.
Qualitative Enzyme-Linked Immunosorbent Assay (ELISA)/Quantitative Gas Chromatography-Mass Spectrometry (GC/MS)/Quantitative Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS).
Since meconium begins to form in the fetal gut about the fourth month, this procedure can provide up to a 20 week history of fetal drug exposure.
If the specimen screens positive, then confirmation/quantitation by GC/MS and/or LC-MS/MS will be performed.
Specimens are screened for the presence of Amphetamines, Barbiturates, Benzodiazepines, Buprenorphine, Cocaine, Marijuana, Methadone, Opiates, and Phencyclidine.
