April 16, 2026—Labcorp launched the Labcorp Fentanyl Urine Visual Test. The test assesses fentanyl exposure by detecting norfentanyl, which can remain present in urine up to 48 hours after initial exposure. It delivers results in 10 minutes and is FDA-cleared for use by qualified professionals in CLIA-certified settings. Results are intended for preliminary rapid screening purposes and should be confirmed using appropriate laboratory methods.
The test is available through Labcorp Point of Care, previously known as Medtox Diagnostics.
