MET (Methamphetamine)
Methamphetamine is a powerful stimulant, most often illicit (crystal meth) but occasionally prescribed as Desoxyn.
Detection window: Usually detectable in urine for 2-4 days after use, at a 500 ng/mL screening cutoff.
Prescriptions: Certain prescriptions and some cold-medicine ingredients can trigger a screen; lab confirmation reports measured levels, which distinguishes a valid prescription.
How Testr tests for it
This panel is part of every Testr visit. A certified collector handles the collection at your home, checks specimen temperature, and reads a clinical 14-panel cassette on the spot. For measured levels rather than a positive/negative read, add laboratory confirmation: a CAP-accredited lab quantifies the result by LC-MS/MS, with measured levels on the report.
