The Multi-Drug Test Kit (http://hqtestkits.com) is an immunoassay based on the principle of competitive binding. Each drug test panel is designed to a sensitivity level known
as a cut-off point. This means that if the result is negative, it could indicate no drugs are present or the drug concentration is below the cut-off point. Please also
note that a number of factors could influence the results, for example the individual’s drug absorption rate, metabolism rate, distribution in the body, excretion rate, drug quantity and drug quality.
