CAUTION: Not all fentanyl test strips work the same.

These new strips, manufactured by the US-based company WHPM, utilize a superior antibody with higher specificity to fentanyl and its analogs. This means that unlike the older BTNX FYL strips most of us have been using, the new FEN strips do not produce false positives with methamphetamine, MDMA, cocaine, or methadone, when used according to the instructions.

This has verified this through field testing, a commissioned study at Kara Lynch’s lab at the University of California San Francisco (UCSF), and a research collaboration with Marya Lieberman’s lab at the research collaboration with Marya Lieberman’s lab at the University of Notre Dame (ND). of Notre Dame (ND).

HIGHER SENSITIVITY TO FENTANYL

The UCSF study also determined that these new strips have a sensitivity to fentanyl that is 10 times greater than the Rapid Response strips. A newly published study by researchers from Johns Hopkins University similarly revealed that the Rapid Response strips, advertised to have a detection threshold of 20 ng/ml, actually have a detection threshold of 200 ng/ml.
