Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms of cocaine use, such as rapid heart rate, confusion, or if you’re suspected of drug use in a workplace or legal setting. It can also be part of routine screening for substance use disorders or pre-employment checks.

What to Expect During the Test

You’ll provide a urine sample in a sterile container. The lab will analyze it using a specialized method to detect cocaine metabolites. No special preparation is needed, but avoid drinking excessive fluids before testing if instructed.

How the Results Are Interpreted

Results are typically reported as a positive or negative for cocaine metabolites. A positive result indicates recent use, but it doesn’t confirm the exact amount or timing of use. Follow-up testing may be needed for confirmation.

What the Results Mean for You

A positive result means cocaine or its breakdown products were found in your urine. This doesn’t necessarily mean you’re addicted, but it signals recent use. Discuss your results with your healthcare provider to understand next steps, such as counseling or treatment options.
