Why This Test Is Done

Your healthcare provider may order this test if you’re taking oxycodone for pain relief, if you’re being monitored for substance use, or if there are concerns about potential misuse. It can also be part of a broader evaluation for addiction or compliance with treatment plans.

What to Expect Before the Test

No special preparation is needed. You’ll collect saliva samples over 24 hours, typically by spitting into a container at specified times. Follow your provider’s instructions carefully to ensure accurate results.

How the Test Works

The collected saliva is analyzed using a sensitive laboratory method (likely high-performance liquid chromatography or immunoassay) to measure the concentration of oxycodone. This helps determine how much of the drug was present in your system during the period.

What the Results Mean

Results provide a snapshot of your recent oxycodone exposure. High levels may indicate recent use, while lower levels could suggest reduced intake or metabolism. Always discuss results with your healthcare provider.
