Urine Specimen Drug Testing 

Urine drug tests serve as effective tools to identify recent instances of drug usage or misuse. The term drug usage applies to the consumption of illegal substances such as heroin or cocaine, while drug misuse pertains to the inappropriate or non-prescribed use of medications.

​

Primarily, urine drug tests are employed to monitor potential drug usage or misuse within the workplace environment. Employers might mandate a urine drug test during the pre-employment screening process, for routine or random employee drug checks, or when drug consumption is suspected due to certain symptoms or incidents at the workplace.

​

Moreover, physicians might order urine drug tests for patients prescribed potentially misusable medications, ensuring that the patient is following the prescription accurately. Prescription drugs that are often misused include opioids, central nervous system depressants used for treating anxiety and sleep disorders, and stimulants used for managing attention-deficit hyperactivity disorder (ADHD). Urine drug tests can detect the drug, its metabolites, or other biomarkers indicative of drug usage or misuse. A biomarker is any substance that can be measured in the body following drug consumption. A metabolite, a specific type of biomarker, persists in the body as the drug gets metabolized and eliminated.
