Case of 25 Tests
EZ Drug Test Split Key Cup is 99% Accurate and gives results in minutes! Fully integrated cup where the tester does not have to come in contact with the urine.
The Integrated cup has a new key feature. No more turning, simply put the key in and push. The collector retains control of the testing process and can time the results to insure proper interpretation.
Separation of the sample from the remainder of sample sent for confirmation. No contamination of sample. New smaller size cup reduces shipping costs, decreases storage requirements. The cup has an easy Xerox feature where the cup can be laid down on its side and copied for retention of results with no leakage. New easy to open top for the confirmation lab. The cup is fully integrated where the tester does not have to come in contact with the urine.
What is adulteration?
Adulteration is the tampering of a urine specimen with the intention of altering the test results. The use of adulterants can cause false negative results in drug tests by either interfering with the screening test and/ or destroying the drugs present in the urine. Dilution may also be employed in an attempt to produce false negative drug test results.
One of the best ways to test for adulteration or dilution is to determine certain urinary characteristics such as creatinine, pH, and specific gravity and to detect the presence of glutaraldehyde, nitrite and oxidants /pyridinium chlorochromate (PCC) in urine.
- Creatinine is a waste product of creatine; an amino-acid contained in muscle tissue and found in urine. 1 A person may attempt to foil a test by drinking excessive amounts of water or diuretics such as herbal teas to “flush” the system. Creatinine and specific gravity are two ways to check for dilution and flushing, which are the most common mechanisms used in an attempt to circumvent drug testing. Low creatinine and specific gravity levels may indicate dilute urine. The absence of creatinine (<5mg/dl) is indicative of a specimen not consistent with human urine.
- Specific gravity tests for sample dilution. The normal range is from 1.003 to 1.030. Values outside this range may be the result of specimen dilution or adulteration.
- Nitrite tests for commonly used commercial adulterants such as Klear or Whizzies. They work by oxidizing the major cannabinoid metabolite THC-COOH.2 Normal urine should contain no trace of nitrite. Positive results generally indicate the presence of an adulterant.
- Glutaraldehyde tests for the presence of an aldehyde. Adulterants such as UrinAid and Clear Choice contain glutaraldehyde which may cause false negative screening results by disrupting the enzyme used in some immunoassay tests.³ Glutaraldehyde is not normally found in urine; therefore, detection of glutaraldehyde in a urine specimen is generally an indicator of adulteration.
- pH tests for the presence of acidic or alkaline adulterants in urine. Normal pH levels should be in the range of 4.0 to 9.0. Values outside of this range may indicate the sample has been altered.
- Oxidants/PCC (Pyridinium Chlorochromate) tests for the presence of oxidizing agents such as bleach and hydrogen peroxide. Pyridinium chlorochromate (sold under the brand name UrineLuck) is a commonly used adulterant.³ Normal human urine should not contain oxidants or PCC.
