Confirmation testing either via LC/MS (Liquid Chromatography/ Mass Spectometry) or GC/MS  (Gas Chromatography/Mass Spectometry)  is accepted as the “gold standard” for identification of drug analytes. It is used to confirm presumptive positive immunoassay drug testing. Confirmation testing is accepted in both scientific and legal arenas as one of the most powerful techniques in determining drug analytes.
