Perinatal Drug Testing using Umbilical Cord Tissue

During pregnancy, some drugs that a mother takes can pass from her blood stream, through the placenta, and to the fetus. Understanding in utero drug exposure is important for proper case management. Maternal urine screens can only provide a record of recent exposure.

Historically, newborn drug testing was performed using meconium. However, problems can exist with meconium—it may take days to pass, the newborn may not produce enough to test or, in some cases, the meconium is passed in utero making collection impossible. For these reasons, using the umbilical cord for drug testing may have a more rapid return to the clinician as specimens can be collected and sent for testing immediately following birth.
