Are rapid drug tests as accurate as a GC/MS SAMHSA Lab Test?

Our drug tests are qualitative, which means it only determines the presence of drugs at detection, limits comparable to SAMHSA cut-off concentration. GC/MS, which costs more, quantifies the concentration of drugs in the sample. Given the purposes of most drug testing (pre-employment, post-accident, random) is to detect the presence of drug use and not determine the amounts ingested, our rapid drug test satisfies the needs of almost all Drug Screening Programs.
