Collection Instructions

Specimen:See Collection Instructions
Optimal Volume:8 inches umbilical cord tissue. Caution must be used when collecting specimen to ensure no ethanol-containing personal care products (i.e., hand sanitizers, wipes, mouthwash) are used directly on the specimen or are nearby during collection.
Minimum\Peds Volume:If drug detection panel and marijuana metabolite testing are also requested, all three tests can be submitted on a single 8 inch cord sample.
Collection Instructions:
  1. Cut a 8 inch section of the umbilical cord.
  2. Drain and discard any blood by sliding the cord through your pinched finger and thumb.
  3. Rinse the exterior of the cord sigment with normal saline or sterile water.
  4. Pat the cord dry and trnasfer specimen to the sterile, leakproof container; apply red tamper-resistant tape over the lid.
Causes for Rejection:Cords soaking in blood or other fluid. Formalin-fixed. Tissue that is obviously decomposed.

Interpretive

Reference Range:By report.
Use:This test is designed to detect and document exposure that occurred during approximately the last trimester of a full term birth, to a common ethanol (alcohol) metabolite. Alternative testing is available to detect other drug exposures. The pattern and frequency of drug(s) used by the mother cannot be determined by this test. A negative result does not exclude the poosiblity that a  mother used drugs during pregnancy. Detection of drugs in umbilical cord tissue depends on extent of maternal drug use, as well as drug stability, unique characteristics of drug deposition in umbilical cord tissue, and the performance of the analytical method. Drugs administered during labor and delivery may be detected. Detection of drugs in umbilical cord tissue does not insinuate impairment and may not affect outcomes for the infant. Interpertive questions should be directed to the laboratory.
For medical purposes only; not valid for forensic use untill testing was performed within Chain of Custody process.
