Do rapid test results hold up in court?

Rapid drug tests provide only a preliminary analytical test result. A more specific alternate
chemical method must be used in order to obtain a confirmed analytical result- gas chromatography (mass
spectrometry) (GC/MS) is the preferred confirmatory method. Any result taken to court, must be
confirmed by a SAMHSA certified Lab. SAMHSA’s list Of Certified Labs For GC/MS Testing.
