One Step Cotinine Test has set the screen cut-off for positive specimens at 100 ng/mL for cotinine as the calibrators. The test device has been proved to detect above the cut-off level of the target drugs in urine at 5 minutes.
B. Specificity and cross reactivity
To test the specificity of the test, the test device was used to test cotinine and other components of the same class that are likely to be present in urine, All the components were added to drug-free normal human urine. These concentrations below also represent the limits of detection for the specified drugs or metabolites.

INTENDED USE
The One Step Cotinine Test is a lateral flow chromatographic immunoassay for the detection of cotinine at the cut-off level of 100 ng/ml. The assay is intended to verify an intoxication in patients. It provides a qualitative, preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary results are positive.

What is drug addiction?
Drug addiction is a chronic brain disease. It causes a person to take drugs repeatedly, despite the harm they cause. Repeated drug use can change the brain and lead to addiction. The brain changes from addiction can be lasting, so drug addiction is considered a "relapsing" disease. This means that people in recovery are at risk for taking drugs again, even after years of not taking them. Drug use is dangerous. It can harm your brain and body, sometimes permanently. It can hurt the people around you, including friends, families, kids, and unborn babies. Drug use can also lead to addiction.
