False positives for fentanyl can occur due to cross-reactivity with other substances in drug tests, such as certain medications or opioids like methadone and buprenorphine. Additionally, factors like testing methods, sample contamination, or the presence of fentanyl analogs that are not specifically detected by the test can contribute to inaccurate results. It's important to confirm positive results with more specific testing methods, such as gas chromatography-mass spectrometry (GC-MS).
