6-Monoacetylmorphine (6-MAM) Confirmation, Chain of Custody, Meconium
Use
This test is useful for detecting in utero heroin exposure up to 5 months before birth. It is specifically designed for legal purposes as it requires a chain of custody to ensure the specimen was handled properly. The test is appropriate for use in legal settings where evidence of illicit drug use during pregnancy can be critical, such as court proceedings related to the possible separation of the baby from the mother.
Special Instructions
Not provided.
Limitations
The short half-life of 6-monoacetylmorphine (6-MAM) may prevent its detection in heroin users. 6-MAM is metabolized to morphine, but the presence of morphine alone does not confirm heroin use. It is recommended that the testing be performed using a chain of custody to ensure results are appropriate for legal proceedings.
