Cocaine Urine Drug Screen (Mass Concentration)

Why This Test Is Done

Doctors may order this test to assess recent drug exposure, evaluate substance use disorders, or screen for illicit substance use in medical, legal, or occupational settings. It can also help monitor treatment progress or screen for potential drug-related issues during pregnancy or before certain surgeries.

The test detects cocaine metabolites (chemical byproducts) in your urine using a highly sensitive method. Cocaine breaks down into metabolites like benzoylecgonine, which remain detectable in urine for several days after use.

This test is typically a quick, non-invasive procedure. You’ll provide a urine sample, which is then analyzed in a lab to determine if cocaine or its metabolites are present.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to avoid certain medications or substances that could interfere with results. If you’re pregnant, breastfeeding, or have a medical condition, discuss it with your healthcare provider before the test.

The test result will indicate whether cocaine metabolites were detected. A positive result means the test found evidence of recent cocaine use, but it doesn’t confirm the exact amount or timing of use.

A positive result should be confirmed with additional testing if needed, especially in medical or legal contexts. False positives can occur due to certain medications or other substances, so follow-up testing may be required.
