Methadone Drug Test

This test detects the presence of methadone and its primary metabolite EDDP (2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine) in urine. Methadone is a long-acting synthetic opioid that is not detected by standard opiate immunoassays due to its distinct chemical structure.

A specific methadone assay is required for accurate detection. The test provides a qualitative result indicating whether methadone or EDDP is present above the assay cut-off level.

Methadone testing is essential for monitoring compliance with opioid substitution therapy programmes. Verifying methadone use helps ensure patients are taking their prescribed medication and supports treatment programme integrity.

The test is also relevant for workplace drug screening, clinical toxicology assessments, and forensic evaluations where methadone exposure needs to be documented.

Testing may be relevant for opioid substitution therapy compliance monitoring, workplace drug screening, clinical evaluations, or when methadone use is suspected. Standard opiate tests do not detect methadone.

Consult a healthcare professional for guidance on testing frequency and result interpretation, particularly in the context of prescribed methadone maintenance therapy.
