CR3 Keyless Split Sample Cup Amphetamine-Cocaine is a rapid test for the qualitative detection of dl-Amphetamine (major metabolize of Amphetamine) and Benzoylecgonine, (major metabolite of Cocaine) in human urine at a cutoff concentration of 1000ng/mL and 300ng/mL, respectively.
The 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. It is Intended for over-the-counter and for prescription use.
