Phencyclidine Phencyclidine 25 ng/mL
Tricyclic Antidepressants Nortriptyline 1000 ng/mL
Configuration of the CLUNGENE® Multi-Drug Test Dip Card can consist of any combination of the above listed drug analytes.
The test may yield positive results for the prescription drugs Buprenorphine, Oxazepam, Secobarbital, Nortriptyline and Oxycodone when taken at or above prescribed doses. It is not intended to distinguish between prescription use or abuse of these drugs. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary result is positive. 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 or LC/MS is the preferred confirmatory method.
For in vitro diagnostic use only.
