Frequently Asked Questions
What does this test detect?
This urine test screens for methamphetamine and its metabolites, commonly known as crystal meth, a Schedule H controlled stimulant drug of abuse.
How long after use can meth be detected in urine?
Methamphetamine is typically detectable in urine for 1 to 3 days after use, though heavy or chronic use may extend detection up to 5 days depending on dose and metabolism.
Is fasting required for this test?
No, fasting is not required for urine drug screening. Collect a midstream clean-catch urine sample in a sterile container.
What is the standard cutoff level for methamphetamine?
The initial immunoassay screening cutoff is typically 500 ng/mL, with confirmatory testing by GC-MS or LC-MS/MS at 100 ng/mL for positive identification.
Can certain medications cause a false positive?
Yes, medications such as bupropion, pseudoephedrine, tramadol, and some ADHD stimulants may cross-react. Confirmatory testing differentiates true positives from cross-reactivity.
