Urine drug tests are qualitative screening devices, which means they only determine the presence of drugs at detection limits comparable to SAMHSA cut-off concentration. GC/MS (Das Chromatography / Mass spectroscopy) is a laboratory technique that uses sophisticated equipment quantifies the concentration of drugs in the sample. This technique takes time and is very expensive.
