How Laboratories Detect Counter Measures
Labs suspect all samples that appear clear of being watered down. To ensure the sample has not been tampered with, labs run creatinine levels, pH levels and Specific Gravity tests to determine if your specimen contains too much water. Expect to be discovered if you drank excessive amounts of water or other fluids to attempt to dilute or mask the level of THC in your urine.
Certified collectors verify that the temperature of your urine sample is between 90 and 100 degrees. A report is noted on your Custody and Control Form if it’s too high or too low, and your specimen is then either disposed of (you then have to submit an additional specimen while being observed) or reported as a failed drug test. Many test-takers employ the use of disposable pocket hand warmers to keep their samples warm.
Creatinine is a substance produced by your body, and it shows up in urine. If someone substitutes with something other than urine, like Mountain Dew, they will test negative for drugs. However, the donor will not get away with it because Mountain Dew contains zero creatinine and that will definitely trigger a “not human urine” result. Creatinine levels drop below normal when people dilute their urine. This test is to ensure that the subject didn't drink unusually high quantities of water. Eating foods rich in protein like red meat will slightly increase creatinine levels. You do need to allow your body enough time (3-4 days) to convert this protein into creatinine. There are creatine supplements available at most health food stores; bodybuilders use it to help with muscle performance.
pH is often changed when people spike their sample with household products. NeonJoint strongly discourages doping your urine, as pH will certainly be tested. Any cleaning product added to the urine will alter the pH level and is a significant indicator that the specimen has been adulterated. This will net you a positive test result or a retest with an observer.
A low specific gravity indicates that a sample has been tampered with. Specific gravity is the indicator that there is way too much water in the urine to obtain an accurate measurement of what is actually contained in the urine. Labs want to test urine, not water. If the levels are too far outside of the normal range, the specimen is reported as Diluted. If the specimen is so far outside the normal range for human urine or it contains a foreign substance that cannot possibly be human, it is reported as Adulterated. An adulterated result is the same as a positive result.
Neither age nor gender can be tested during a urinalysis. Both of these are popular myths.
