Why is confirmation testing required, cant I just rely on the InstaCup test result?
The InstaCup is only a screening device, an indicator that drug use may be present. The GC/MS confirmation test at our SAMHSA certified laboratory confirms for the specific drug(s) in question. It also provides employers with written proof from a certified lab of a positive drug test result and stores the positive specimen for one year in case the donor requests a retest.
