The 2 Drug Screen Urine Test Kit is an immunochromatographic assay for rapid drug testing, qualitative detection of drugs and their principal metabolites in urine at specified cut-off concentrations: THC / Meth (Ecstasy)

Cocaine Drug Urine Test is a simple one step test for the rapid, qualitative detection of Cocaine and primarily benzoylecgonine as metabolites in urine. The cutoff of the test is 300 ng/ml of Cocaine. It is the same as the SAMHSA recommended cutoff. The cocaine test provides only a preliminary analytical result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography, mass spectrometry (GC/MS) is the preferred method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.

Cocaine, derived from the leaves of the coca plant, is a potent central nervous system stimulant and a local anesthetic. Cocaine induces euphoria, confidence and a sense of increased energy in the user; these psychological effects are accompanied by increased heart rate, dilation of the pupils, fever, tremors and sweating. Cocaine is used by smoking, intranasal, intravenous or oral administration, and excreted in the urine primarily as benzoylecgonine in a short time. Benzoylecgonine has a longer biological half-life (5-8 hours) than cocaine (0.5-1.5 hours) and can generally be detected for 24-80 hours after cocaine use or exposure. The cocaine test is based on the principle of the highly specific immunochemical reactions between antigens and antibodies, which are used for the analysis of specific substances in biological fluids. The sensitivity of the test is 300 ng/ml of Cocaine.

UrineCheck 6 is based on detection methods that can identify the presence of additives, adulterants and masking agents that are added to urine.

UrineCheck 6 Drug Adulteration Test Strip:

Creatinine:

Testing for sample dilution. In this assay, creatinine reacts with a creatinine indicator under alkaline conditions to form a purplish-brown color complex. The concentration of creatinine is directly proportional to the color intensity of the test pad.

Glutaraldehyde:

Testing for the presence of exogenous aldehyde. In this assay, the aldehyde group on the glutaraldehyde reacts with an indicator to form a pink color complex.

Nitrite:

Testing for the presence of exogenous nitrite. Nitrite reacts with an aromatic amine to form a diazonium compound in an acid medium. The diazonium compound, in turn, couples with an indicator to produce a pink-red color

Oxidants:

Testing for the presence of oxidizing reagents. In this reaction, a color indicator reacts with oxidants such as bleach, hydrogen peroxide or pyridinium chlorochromate to form a blue color complex. Other colors may indicate the presence of other oxidants.

pH:

Testing for the presence of acidic or alkaline adulterant. This test is based on the well-known double pH indicator method that gives distinguishable colors over a wide pH range. The colors range from orange (low pH) to yellow and green to blue (high pH).

Specific Gravity:

Testing for sample dilution. This test is based on the apparent pKa change of certain pretreated polyelectrolytes in relation to the ionic concentration. In the presence of an indicator, the colors range from dark blue or blue-green in urine of low ionic concentration to green and yellow in urine of higher ionic concentration
