FaStep Marijuana Tests are immunochromatographic assays for the qualitative determination of 11-nor-A9-THC-9-COOH in human urine at a cut-off concentration of 50ng/mL. The test is available in a Strip format, a Panel Dip format, a Quick Cup format and a Turn-Key Split Cup format.
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.
FaStep Methamphetamine Tests are immunochromatographic assays for the qualitative determination of methamphetamine in human urine at a cut-off concentration of 1000 ng/mL. The test is available in a Strip format, a Panel Dip format, a Quick Cup format and a Turn-Key Split Cup format.
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.
