That's where I'm not as sure. When I worked in the ER, they did both the qualitative and quantitative tests in the lab for several different drugs and substances in patient's blood and/or urine. The tests for THC were fool-proof because of the reagents used and I've only heard of those detox products being used to mask THC. Is that right? Or are there some for other drugs they hide as well?
All I know is that they needed to ensure we knew what drugs of abuse or pharmaceutical drugs were in a patient's system when and if possible because 1) the drugs could alter a patient's mental status and responsiveness (something we needed to be able to determine in order to know how their injury may have affected those things) and 2) it could affect what other medicines the patient could receive.
As far as a school's method of testing, it could be something that they send out to a lab or it could be some type of field test like cops use -- some simple qualitative test strip or additive that just determines the presence of a drug by changing color. I'm not sure how good those will be.
