This urine test screens for opiates, the natural opioid compounds such as morphine and codeine, and confirms any presumptive positive result. The immunoassay provides a fast initial answer, while the confirmation step verifies and identifies the compound present. Urine is commonly used for opiate testing because metabolites remain detectable for a reasonable window after use. Including confirmation with the screen helps verify the finding and identify which opiate is present.

• Opiates (screen) Natural opioid compounds such as morphine and codeine detected by immunoassay in urine.
• Opiate confirmation A specific analytical method used to verify and identify a presumptive positive opiate screen.

• A clinician wants to evaluate possible opiate use with a verified result.
• You are in a monitoring or treatment program that includes opioid testing.
• You take a prescribed opiate and its presence needs documentation.
• An initial opiate screen requires confirmation before it is reported.

• No fasting is required for this urine test.
• Provide a fresh sample at the collection site.
• Report all opioid medications and codeine-containing products.
• Avoid drinking excessive water right before collection to prevent dilution.

A negative result suggests opiates were not detected above the cutoff. A positive screen is presumptive and is confirmed to identify whether the finding is morphine, codeine, or another opiate. Poppy seeds and some medications can occasionally affect screening, so confirmation adds clarity. Discuss the confirmed result with a healthcare provider, particularly if you take prescribed opioids.
