Cocaine and Metabolite Confirmation, Chain of Custody, Meconium
Use
The test is useful for detecting in utero drug exposure to cocaine and its metabolites up to 5 months before birth. The inclusion of a chain of custody requirement ensures that the specimen is managed under controlled conditions to prevent tampering, which is critical for legal proceedings that may result from the test results, especially in cases where evidence of illicit drug use during pregnancy could lead to legal actions such as separating the baby from the mother.

Limitations
Specimen arriving with a broken seal does not meet chain of custody requirements and may not be accepted.
