## Indications for use
First Sign™ Drug of Abuse Tests are immunochromatographic assays for the qualitative determination of Amphetamine (d-amphetamine), Cocaine (Benzoylecgonine), and Marijuana (11-nor-A9-THC-9-COOH ) in human urine at cut-off concentrations of 1000 ng/mL, 300 ng/mL, and 50 ng/mL, respectively. The tests are available in a Cup format and a Dip Card format. The tests provide 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. The tests are intended for over-the-counter and for prescription use.
