## Indications for use
CR3 Keyless Split Sample Cup Oxycodone-Cannabinoids is a rapid test for the qualitative detection of Oxycodone and Cannabinoids in human urine at a cutoff concentration of 100 ng/mL and 50 ng/mL, respectively. The test is the first step in a two-step process. The second step is to send the sample for laboratory testing if preliminary positive results are obtained. The test is intended for over-the-counter and for prescription use. The test may yield preliminary positive results even when the prescription drug Oxycodone is ingested, at prescribed doses; it is not intended to distinguish between prescription use or abuse of this drug. There is no uniformly recognized cutoff concentration level for Oxycodone in urine. The CR3 Keyless Split Sample Cup Oxycodone-Cannabinoids test provides only preliminary test results. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. GC/MS is the preferred confirmatory method. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive. For in vitro diagnostic use only.
