The Canadian version of QuickFix passes these tests.
If the job entails working with equipment or other hazardous jobs they fall under the dominion of the DOT federal protocols. For any of those tests synthetic works fine. And for most others it works fine. The problem is with some drug testing facilities are offering the added test to see if its fake or not. The Canadian version of QuickFix is supposed to even pass those.
Mine are always DOT type tests so I don't bother with the canadian version.
killerweed420 Reviewed by killerweed420 on . Does labcorp ROUTINELY perform specimen validity testing? In order to protect my privacy, yesterday I tested at LabCorp using synthetic urine. The substitution went off without a hitch, but now I am reading from several sources that LabCorp is automatically testing for synthetic. I do not live in a state where synthetic is illegal, temp was right, etc. The LabCorp website says this test is "available" but not that it is routinely done. Does anyone know what the current LabCorp procedure is? This is a REALLY good job for me. Am I screwed? Rating: 5
