What false positive will olanzapine give?

Olanzapine can potentially cause false positive results in drug screenings for substances like amphetamines or methamphetamines. This is primarily due to its chemical structure, which may be misidentified by some immunoassay tests. Confirmatory testing, such as gas chromatography-mass spectrometry (GC-MS), is recommended to accurately differentiate between olanzapine and other substances. Always consult with a healthcare professional for specific concerns regarding drug testing.
