Not on the cassette

Substances people ask about that the 14 panels do not screen

Some of the most common questions are about substances the rapid screen was never designed to find. These pages say plainly what the cassette does not cover, and what the laboratory's 81-substance confirmation menu can.

Does kratom or 7-OH show up on a drug test?

Not on the 14-panel screen. Mitragynine and 7-hydroxymitragynine are on the laboratory confirmation menu.

Do shrooms show up on a drug test?

Not on the 14-panel screen. Psilocin, the psilocybin metabolite, is on the laboratory confirmation menu.

Does K2 or Spice show up on a drug test?

Not on the 14-panel screen and not caught by the THC panel. Four synthetic cannabinoids are on the laboratory confirmation menu.

How to read a drug test panel page

Each page gives the same three facts about one panel of the urine drug test: what the panel screens for, how long that substance typically stays detectable in urine, and the screening cutoff, which is the level at or above which the on-site cassette reads positive. Below the cutoff the panel reads negative even when a trace is present, so the cutoff matters as much as the number of days.

Detection windows are typical ranges rather than guarantees. How much was taken, how often, body weight and hydration all move them. Where a legitimate prescription can produce a positive, the page says so: laboratory confirmation reports measured levels rather than a bare positive, and every laboratory report goes to a Medical Review Officer (MRO), a physician who reviews laboratory-confirmed results and accounts for valid prescriptions before the report is released.

Wondering what MOP, FYL or mAMP means on a cup or a report? Every code, with its cutoff and detection window, is on one page: drug test abbreviations, decoded.
