Oral fluid or saliva testing results for the most part mimic that of blood. The chart depicts the longer detection times of the metabolites. For example, heroin and cocaine can only be detected for a few hours after use, but their metabolites can be detected for several days in urine. For ease of use, the detection times of metabolites have been incorporated into each parent drug. The detection windows depend upon multiple factors: drug class, amount and frequency of use, metabolic rate, body mass, age, overall health, and urine pH. 2.11 Occupational harm reduction strategies.2.5 Saliva drug screen / Oral fluid-based drug screen.Numerous other methods with varying degrees of accuracy, sensitivity (detection threshold/cutoff), and detection periods exist.Ī drug test may also refer to a test that provides quantitative chemical analysis of an illegal drug, typically intended to help with responsible drug use. BAC tests are typically administered via a breathalyzer while urinalysis is used for the vast majority of drug testing in sports and the workplace. Major applications of drug testing include detection of the presence of performance enhancing steroids in sport, employers and parole/ probation officers screening for drugs prohibited by law (such as cocaine, methamphetamine, and heroin) and police officers testing for the presence and concentration of alcohol ( ethanol) in the blood commonly referred to as BAC (blood alcohol content).
For other uses, see Drug testing (disambiguation).Ī drug test is a technical analysis of a biological specimen, for example urine, hair, blood, breath, sweat, or oral fluid/saliva-to determine the presence or absence of specified parent drugs or their metabolites.
