Why This Test Is Done

Your healthcare provider may order this test if you have symptoms of cocaine use, such as anxiety, rapid heartbeat, or trouble sleeping. It can also be part of a broader evaluation for substance use, workplace or legal requirements, or pre-surgery screening.

How the Test Works

Cocaine breaks down in the body into metabolites (chemical byproducts), which are excreted in urine. This test measures these metabolites using advanced laboratory techniques like chromatography or immunoassay to detect their presence.

Sample Collection

A urine sample is collected in a sterile container. You may be asked to provide a clean-catch sample or use a urine collection kit provided by your healthcare team.

Test Results Interpretation

Results are qualitative (positive/negative) or quantitative (amount present), depending on the test type. Positive results indicate recent cocaine use, but they don’t confirm the exact amount or duration of use.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

A positive result suggests recent cocaine exposure and may prompt further evaluation, such as additional tests or counseling. It can also impact decisions about treatment, employment, or legal proceedings.
What does a positive result mean?
A positive result means your urine contains cocaine metabolites, indicating recent use. This doesn’t prove you used cocaine recently, but it does suggest exposure within days. False positives can rarely occur due to other medications or conditions.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on your lab’s processing time.
Yes, you can drink water before the test, but avoid excessive fluid intake to ensure a concentrated urine sample. Follow any specific instructions your healthcare provider gives you.
