COMMON METHODS OF DRUG TESTING
Many methods may be employed to carry out the process of testing drugs. Listed and explained below are but a few of those strategies that may be employed:
Presumptive Substance Test
This is a test that is taken as a tentative measure. It is not at all intended to be deemed final and complete. Instead, some confirmatory tests have to be performed late to validate or invalidate the results that are obtained from these findings. The purpose of many of the different types of testing is to ascertain the existence of any trace levels or other harmful substances that may exist in the body.
