Opiate Confirmation, Chain of Custody, Meconium
Use
This test is useful for detecting maternal prenatal opiate/opioid use up to 5 months before birth. It is especially crucial in legal settings where the evidence of illicit drug use during pregnancy can be cause for separating the baby from the mother. The test ensures the rights of the individual contributing the specimen are protected by maintaining a chain of custody, thus limiting the opportunity for specimen tampering and ensuring results are appropriate for legal proceedings.
Special Instructions
Not provided.
Limitations
The test cannot determine the exact timing or amount of exposure. It should not be used to directly assess the degree of impairment or maternal behavior. Potential for diagnostic confusion exists if specimens are not collected following strict chain-of-custody procedures. Evidence of illicit drug use during pregnancy can lead to legal actions; thus, it is essential to maintain the integrity of the process to ensure legally sound results.
