The Drug Adulteration Strips are a fast dip-and-read test for the determination of diluted or adulterated urine specimens. They are an important prescreening test for any drug testing program.
Donors may try to tamper with or manipulate a urine specimen with the intention of causing a false negative result. This is usually achieved by substitution or the addition of adulterants (including so called ‘masking agents’) that interfere with the screening test and/or destroy the drugs within 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 pH and specific gravity and to detect the presence of oxidants/PCC, specific gravity, pH, nitrite, glutaraldehyde and creatinine in urine.
Some of our urine cups are equipped with integrated temperature and adulteration strips; however, you can also buy these separately for use with any of our urine tests.
The one step dip and read specimen validity test semi-quantitatively analyzes a urine specimen for 7 parameters on 6 reactive pads in one easy step.
  • 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.
  • Nitrites - 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. 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.
  • 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. Tests for the viscosity of the urine sample
  • Oxidants and PCC - 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. Normal human urine should not contain oxidants or PCC.
Results are obtained by comparing the color on each of the test pads with the corresponding pad on the container color chart label.
