Urine Drug testing

CLIO lab tests urine samples for the presence of drugs. Urine tests have a longer detection period, typically about twice as long, as blood or saliva tests. Urine is the preferred specimen for drug testing primarily because it is a low-cost monitoring strategy that will detect most drugs for 1 to 3 days post exposure. The advantages of using urine specimen for drug testing can be summarized as follows:

  • Non-invasive
  • Ample volume
  • Drugs and drug metabolites found in urine are usually stable
  • Drugs and their metabolites are often present in higher concentrations in urine than in other biological materials
  • Detectable in urine for relatively long period of time (benzodiazepines, up to 21 days; cannabinoids, up to 60 days)
  • Presence of metabolites, in addition to parent drug, provides further evidence of drug use
  • Readily preserved by refrigeration or freezing
  • Analysis relatively simple because of absence of proteins and cellular material in urine
