NO KNOWN FALSE POSITIVES
DanceSafe is proud to introduce a new and improved fentanyl test strip to the harm reduction community. 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 Rapid Response strips most of us have been using, our new strips do not produce false positives with methamphetamine, MDMA, cocaine, or methadone, when used according to the instructions.

We have 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 University of Notre Dame (ND).
