With urine drug test being the most common pre-employment or employment test, it is very important to know how to pass one. There are many ways to get the results that you want, but sometimes a chosen path does not turn out to be the right one. For instance, some people prefer flushing, others – substituting, third – adulterating. Is the latter a good idea? Let’s see into the technical details of a standard urine drug test.

Every certified laboratory is required to test each specimen for number of adulterants. Standard pH tests and a test for one or more oxidizing compounds are done to validate a specimen prior to testing it for toxins. The actual term “adulterated specimen” is defined as a “specimen that contains a substance that is not expected to be present in human urine, or contains a substance expected to be present but is at concentration so high that is not consistent with human urine.” People tend to use common household products or commercial chemicals in attempt to defeat a drug test, however, all those non-specialized products that can be added to a sample without lowering the temperature and without changing the color, can be easily detected by the lab.

To prevent an embarrassing situation, simply do not experiment with anything you might find under your sink. There are a number of specialized products that are created solely for the purpose of defeating a test, and also, try the Urine Check 7 strip that will tell you if your sample will pass for such parameters as creatinine, nitrite, glutaraldehyde, pH, specific gravity, bleach and pyridinium chlorochromate.
