Why Is This Test Done?

Your healthcare provider may order this test if you are taking oxycodone regularly, experiencing suspected opioid use, or if there is concern about drug diversion, misuse, or compliance with treatment plans. It can also be used in workplace drug screening or legal investigations.

What Does the Test Measure?

The test detects the presence of oxycodone in your urine, which can indicate recent ingestion. Oxycodone is metabolized in the body, and its metabolites may appear in urine for several days after use.

Sample Collection and Preparation

You will collect a urine sample in a sterile container provided by your healthcare facility. The sample should be collected under supervision to ensure accuracy, especially in controlled settings like workplace testing.

What to Expect During the Test

The test is typically a simple urine collection process. The sample is then analyzed in a laboratory using a sensitive detection method to measure oxycodone concentration.
