Manufactured by the California-based company, WHPM, and developed over the course of a year with the assistance and expertise of DanceSafe founder, Emanuel Sferios, our fentanyl test strips are specifically designed for harm reduction use (as opposed to urine testing). With a detection cutoff of 10 ng/ml, they are one of the most sensitive test strips on the market. They are also highly selective to fentanyl and its analogs, making them less likely to produce false positives by cross reacting with other, non-fentanyl related drugs.
