What are the different ways in which drugs are tested?

There are five primary types of drug tests: urine, blood, hair, saliva, and sweat.Urine Tests- Detect use primarily within the past weeks, least expensive method ($5-$50 for home version).Saliva Tests-a little more expensive than urine testing, but less than hair or blood. ($15-$75). Detect use primarily within the past few days (up to 5-7 days).Can detect more recent use than other testing methods. Have no nationally accepted standards or cutoff concentrations for detectionHair Tests-currently several times more expensive than urine tests ($100-$250).Detect substance use over a longer period (up to 90 days) but do not usually detect use within the past week. Lab require a sample of hair about the diameter of a pencil and 1.5 inches long.Blood Tests- the most expensive method of testing.Sweat (Patch) Tests-considered a relatively intrusive method of drug testing because they require the wearing of a patch for an extended period of time, still relatively uncommon.Can detect use which would not trigger other tests.
