A positive methadone test can occur from the actual use of methadone, which is a medication commonly prescribed for opioid addiction or chronic pain management. Additionally, certain medications or substances, such as buprenorphine or some over-the-counter drugs, may cause cross-reactivity in immunoassay tests, leading to false positives. Furthermore, environmental factors or contamination can occasionally result in misleading test outcomes. It's essential to confirm positive results with more specific testing methods, such as gas chromatography-mass spectrometry (GC-MS).
