A common method for screening individuals for substance use involves analyzing a sample to detect the presence of five specific classes of drugs. This process typically involves collecting a urine sample, although other biological specimens such as hair, saliva, or blood may also be used. The collected sample is then subjected to laboratory analysis using techniques like immunoassay or gas chromatography-mass spectrometry to identify any drug metabolites.
This type of drug screen is frequently utilized by employers, healthcare providers, and legal entities to ensure safety, compliance, or adherence to treatment plans. Its widespread adoption stems from its relatively low cost, ease of administration, and ability to provide results within a reasonable timeframe. Historically, such testing has played a role in maintaining workplace safety and addressing public health concerns related to drug abuse.
