## Indications for use
InstaStrip Fentanyl Rapid Test (Urine) is intended for the qualitative detection of fentanyl in human urine at the cutoff value of 1.0 ng/mL. The test is intended for over-the-counter (OTC) use. The assay provides only a preliminary analytical result. A more specific alternative chemical method (e.g., gas or liquid chromatography and mass spectrometry) must be used in order to obtain a confirmed analytical result. Clinical consideration and professional judgment should be exercised with any drug of abuse test result, particularly when the preliminary test result is positive.
