The One Step Marijuana (THC) Test Card is an easy and cost-effective solution to detect the presence of Marijuana (THC metabolite) in human urine at a cut-off concentration of 50 ng/ml. When the concentration of marijuana exceeds more than 50 ng/ml, the test yields positive result. Marijuana drug testing kits are offered at a relatively low price by 10% than any other and will provide free shipping for all the orders over $30. Marijuana test cards are FDA approved and are set to SAMHSA cutoff levels.

This test card provides only a 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 positive results are used.
