Home test kits are assays which are pass/fail.

In order to obtain a quantitative value, a GC/MS test must be performed on the sample.
Burnt Toast Reviewed by Burnt Toast on . I am new to drug testing and have some questions I have applied for a security job that requires a pre employment drug screening. Unfortunately, I don't know what type of screening they will impose (urine, saliva, etc) so I can't really prepare yet because I don't know what detox product to buy. My questions are: 1. What are the chances that they will do the drug test during the time of the interview? 2. Will they give me advanced notice of when the drug test will be and what type of test it will be? Rating: 5
