Why This Test Is Done
Your healthcare provider may order this test if you have concerns about recent cocaine use, are undergoing treatment for substance use disorder, or are part of a monitoring program. Saliva testing is non-invasive and can provide a snapshot of recent drug intake, unlike blood or urine tests that reflect longer-term exposure.
How the Test Works
A small saliva sample is collected, usually by swabbing your inner cheek. The test measures cocaine metabolites (chemical breakdown products) in your saliva over 24 hours, often analyzed using a sensitive immunoassay or similar method to detect even small amounts.
Sample Collection and Preparation
Saliva is collected at specific intervals (e.g., every few hours) or continuously monitored via a device worn in your mouth. The sample is processed in a lab to quantify cocaine metabolites, which are then compared to a reference standard.
What to Expect Before the Test
No special preparation is needed, but avoid chewing gum, smoking, or eating/drinking for a few hours before collection if instructed. If you’re taking medications, discuss them with your provider to ensure they don’t interfere with results.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
