Why This Test Might Be Ordered

Your healthcare provider may order this test if you’re suspected of recent drug use, involved in legal or workplace drug testing, or experiencing symptoms that could be related to substance exposure. It’s often used for quick, non-invasive screening rather than confirming long-term use.

How the Test Works

Saliva contains small amounts of substances from what you ingest or inhale. This test detects cocaine metabolites (chemical breakdown products) in your saliva using a sensitive immunoassay method, which identifies the presence of cocaine without needing precise measurements.

What to Expect Before the Test

No special preparation is needed. You’ll provide a saliva sample, often by spitting into a collection device. The test is quick and painless, typically taking a few minutes.

What the Results Mean

A positive result indicates recent cocaine exposure, but it doesn’t confirm how long ago it occurred. Negative results mean no detectable cocaine metabolites were found in your saliva at the time of testing. Always discuss results with your healthcare provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

This screening test helps identify recent drug use quickly and non-invasively, supporting decisions about treatment, legal proceedings, or workplace compliance. It’s not a diagnostic tool for chronic substance use but can prompt further evaluation if needed.
A positive result may lead to additional testing (like urine or blood) to clarify timing or extent of use. False positives can occur with certain medications or other substances.
How long does it take to get results?
Results are usually available within 15–30 minutes, depending on the lab’s processing time. Your provider will contact you with the outcome.
Can I eat or drink before the test?
Yes, you can eat, drink water, or brush your teeth before the test. Avoiding strong mouthwashes or chewing gum may help ensure accurate results, as some products can interfere with the test.
