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’s also used in workplace drug testing, legal proceedings, or before certain surgeries to ensure safety.

How the Test Works

Cocaine breaks down in the body into metabolites (chemical byproducts), which appear in urine. This test detects these metabolites using a highly sensitive method to confirm cocaine exposure.

What to Expect Before the Test

No special preparation is needed. You’ll provide a urine sample in a sterile container. If testing for recent use, results may reflect exposure within days, depending on how quickly the body processes cocaine.

What the Results Mean

Positive results indicate recent cocaine use, but they don’t prove intent or ongoing use. False positives can occur with certain medications or other drugs. Always discuss results with your provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
