FEN Tests (Fentanyl Tests) that detect fentanyl in urine samples

FEN Tests are designed to detect the presence of fentanyl and its metabolites in urine samples quickly and accurately. These tests are essential tools for identifying fentanyl use, a potent synthetic opioid often involved in overdose cases.

CLIA Waived FENTANYL test with 1 ng/mL Sensitivity

CLIA-waived tests stand out by meeting Clinical Laboratory Improvement Amendments (CLIA) standards, allowing for simple, on-site use in various healthcare and workplace settings without the need for complex lab equipment.
