Why is the Urine Adulteration Test performed?

People try to undermine their drug tests by adding adulterants to their urine specimens.
Several adulterants can cause false negative results in drug tests by interfering with the screening immunoassays.

Result Interpretation


Low creatinine levels may indicate dilute urine.
The absence of creatinine (‹20 mg/dl) is indicative of a specimen not consistent with human urine.

tests for commonly used commercial adulterants such as "Klear" or "Whizzies".
They work by oxidizing the major cannabinoid (marijuana) metabolite THC COOH².
Normal urine should contain no trace of nitrites.
Positive results generally indicate the presence of an adulterant.

Glutaraldehyde is not normally found in urine.
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.

Normal pH levels should be in the range of 4.0 to 9.0. Values outside of this range may indicate sample tampering.

Specific Gravity
Values outside the normal range of 1.005 to 1.025 may be the result of specimen dilution or adulteration.

Normal human urine should not contain Bleach.

Normal human urine should not contain PCC.
