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 screenings, legal cases, or before certain surgeries to ensure safety.

How the Test Works

The test detects cocaine or its breakdown products (like benzoylecgonine) in your urine using a specialized immunoassay method. A small urine sample is collected, and the lab analyzes it for these substances.

What to Expect Before the Test

No special preparation is needed. You’ll provide a urine sample, usually in a private area of the lab or clinic. If you’re taking certain medications or have kidney issues, let your provider know.

What the Results Mean

A positive result means cocaine or its metabolites were found, indicating recent use. A negative result means none were detected. False positives can happen, so confirmatory tests may be needed.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
