Cocaine metabolite screening (24-hour urine)

Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of cocaine use, such as rapid heartbeat, anxiety, or trouble sleeping. It could also be part of a routine screening, pre-employment check, or legal requirement. Some people take this test to monitor substance use before treatment begins or to check for drug use in certain settings like work or school.

What to Expect Before the Test

No special preparation is needed. You’ll provide a urine sample in a private area. If this is part of a workplace or legal screening, follow any specific instructions your employer or organization provides. Avoid drinking excessive water before the test, as it may dilute the sample.

What the Test Results Mean

Positive results indicate recent cocaine use, while negative results suggest no detectable cocaine metabolites in your urine over the past 24 hours. However, results alone don’t confirm the exact amount or timing of use. Follow-up testing or additional questions may be needed for a full assessment.

Possible Risks and Considerations

There are no major risks associated with this test. However, false positives can sometimes occur due to other substances or medications. If you’re unsure about your medical history or taking other drugs, let your healthcare provider know to avoid confusion in results.
