HOW TO DETECT URINE ADULTERATION?

Knowing how easy it is to tamper with urine samples and alter test results. The first objective is to find out if the urine sample is legitimate.

Color: If a urine sample looks clear, one can suspect that it’s watered down and may reject the sample and inform the employer about an adulteration attempt.

Temperature: Urine should be between 91 and 97 degrees. NIDA certified labs will verify temperature. If it isn’t, it is a possibility that water has been added to the cup or a substitution has been added.

Creatinine: Creatinine is a substance produced by vertebrates, and it shows up in urine. If someone substitutes their urine with something other than urine, like Mountain Dew, they will test negative for drugs. The tester will most likely not get away with it because Mountain Dew contains zero Creatinine, and an adulterant test detects Creatinine levels to ensure that the sample is valid. Creatinine levels drop below normal when people dilute their urine. This tests to ensure that the subject didn’t drink unusual amounts of water.

pH: pH is often changed when people spike their sample with household products.

Specific gravity: An unusual specific gravity indicates that a sample has been tampered with.

Age: Age can not be tested using urine. There is a rumor that approximate age can be detected in urine, and is tested in medical insurance exams. It’s a myth. Gender: Gender cannot be tested either. As with age, there is a rumor that gender can be detected in urine, and is tested in medical insurance exams. It’s another myth. It may be argued that a pregnancy test can be used to detect the gender of the urine provider, but the same test is used to detect prostate cancer in males.
