T Cup Urinary Drug Test
This drug screening test also detects the following adulterants in the provided urine sample before the T Cup Urinary Test: Creatinine, Nitrite, Glutaraldehyde, pH, Density, Oxidants, Bleach and Pyridinium Chlorochromate.
It is a quick, one-step test for the qualitative detection of psychoactive drugs and their major metabolites in the urine at a specific detection threshold.
The urinary drug test also detects the presence of adulterants in the sample such as nitrite, glutaraldehyde, bleach, pyridinium chlorochromate and other oxidizing agents. This test also makes it possible to determine whether the sample is contaminated by adulterants acid (vinegar) or basic (ammonia), according to the pH indicator.
Operation
The Urinary Rapid T Cup Urine Screening Test is a competitive assay for the detection of certain drugs in a provided urine sample. This urine screening test is performed using an absorbing chromatographic device in which the drugs, or their metabolites present in the sample, compete with their respective conjugates to bind to a limited number of sites of the antibody-dye conjugate.
During the test, the urine sample migrates upwards by capillary action, mixes with the antibody-dye conjugate and passes through the pre-coated membrane. When the concentration levels are equal to or greater than the targeted threshold, the substance binds to the antibody-dye conjugate preventing it from binding to the pre-coated protein-drug complex in the test region (T). This prevents the development of a distinct colored band in the test region,potentially indicating a positive result.
When the sample tested is at or below the targeted threshold (the detection sensitivity of the assay), the antibody-dye conjugate binds to the pre-coated drug-protein complex in the test region (T) of the device. This results in a colored line, which, regardless of its intensity, will show a negative result.
The test also detects for the presence of adulterants in the urine sample such as nitrite, glutaraldehyde, bleach, pyridinium chlorochromate and other oxidizing agents. This test also makes it possible to determine whether the sample would be contaminated by adulterants acid (vinegar) or basic (ammonia), according to the pH indicator.
