Catching a Cheater on a urine drug screening

Adulteration is the tampering of a urine specimen with the intention of altering the test results. Adulterants are used to interfere with the test results. The addition of chemicals can cause a false negative or destroy the drugs present in the urine, additionally, dilution is another commonly used method for producing a false negative on a test.

An effective method for detecting the use of adulterants or dilution is to determine certain urinary characteristics such as Creatine, pH and Specific Gravity. It is also important to look for the presence of Glutaraldehyde, Nitrates and Oxidants – Pyridinium Chlorochromate in the urine.

Adulterant strips, like those offered by EZ Test Cup, are a 1 minute color comparison screening which detect Creatine, Nitrite, Glutaraldehyde, pH, Specific Gravity, Oxidants and Pyridinium Chlorochromate in human urine. After the strip has been dipped in urine, the colors rendered are compared to the colors on the canister which will show if any adulterants are present in the urine.

A quick online search for “how to beat a drug test” will return over 100 million results. The most common suggestion is dilution, followed by a huge variety of other methods. Detecting that someone has tampered with a sample is rather easy.

The very first indicator that a sample may be altered is the temperature. Every EZ Test Cup has a built in thermometer for this reason. If the temperature is not within the appropriate temperature range, further testing should be done quickly. A suspicious sample should be tested for adulterants within 2 at room temperature or 4 hours if the sample is refrigerated.

The use of Adulterant Strips is proven method for catching cheaters. Drug users will go to extremes to pass a test. Do you have a great story of how someone tried to beat a test? A follow up blog could list the creative and extreme measures used to pass a drug test.

Finally, the nitty gritty. What do the test results mean?

CRE – Creatinine: In short, low Creatinine levels and low Specific Gravity are indicative of dilution. People will drink massive amounts of water, herbals teas and take diuretics to “flush” their system of drugs.

NIT – Nitrite: Nitrites are commonly used to oxidize the major cannabinoid metabolite THC-COOH. Normal urine should NOT contain nitrites.

GLUT – Glutaraldehyde: This test checks for the presence of aldehydes which is not normal in urine. Glutaraldehyde is used to disrupt the enzymes used in immunoassay test. If detected it indicates adulteration.

pH – pH: Tests for the presence of acidic or alkaline adulterants in urine. Values outside of the normal range (4.0 to 9.0) may indication tampering.

SG – Specific Gravity: This tests for dilution. Values outside the normal range of 1.003 to 1.030 are likely the result of dilution or adulteration.

OXI/PCC – Oxidants and Pyridinium Chlorochromate: Tests for oxidizing agents such as bleach and hydrogen peroxide which are popular methods of altering samples.
