Dochek® Multi-Drug Urine Test Dipcard Rx is an immunoassay for the qualitative determination of single or multiple drugs in human urine at the following cutoff concentrations:
Drug (Identifier) Cut-off level
Amphetamine (AMP) 1000 or 500 ng/mL
Secobarbital (BAR) 300 ng/mL
Buprenorphine (BUP) 10 ng/mL
Oxazepam (BZO) 300 ng/mL
Cocaine (COC) 300 or 150 ng/mL
2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) 300 ng/mL
Methylenedioxymethamphetamine (MDMA) 500 ng/mL
Methamphetamine (MET) 1000 or 500 ng/mL
Morphine (MOP/OPI) 300 or 2000 ng/mL
Methadone (MTD) 300 ng/mL
Oxycodone (OXY) 100 ng/mL
Phencyclidine (PCP) 25 ng/mL
Propoxyphene (PPX) 300 ng/mL
Nortriptyline (TCA) 1000 ng/mL
Cannabinoids (THC) 50 ng/mL
6-Monoacetylmorphine (6-MAM) 10 ng/mL
Dochek® Multi-Drug Urine Test Dipcard Rx offers any combinations from 1 to 16 drugs but only one cutoff concentration under same drug condition will be included per device. It is intended for prescription use. For in vitro diagnostic use only.
The test provides only preliminary results. Clinical consideration and professional judgment should be applied to any drug of abuse test result，particularly in evaluating a preliminary positive result. To obtain a confirmed analytical result, a more specific alternate chemical method is needed. GC/MS or LC/MS is the recommended confirmatory method.
