The best fentanyl test strips on the market: 

These new strips can detect fentanyl and most of its known analogs in any drug sample, and unlike other strips (such as the older, blue strips), they do not produce false positives with meth, MDMA, or cocaine that contains levamisole. They can also be used to test pressed ecstasy tablets. These strips utilize a superior antibody with greater specificity to fentanyl, and as a result, are the most reliable strips on the market for drug checking and harm reduction purposes.

Please read the instructions carefully. These strips work differently than the older, blue strips. For dilution ratios and more information, see our How to Test Fentanyl page.

CAUTION! Fentanyl test strips from other sources may not detect all necessary fentanyl analogs. Some versions (mostly of Chinese origin) may not function at all.

Special thanks to the respected harm reduction organization, DanceSafe, for allowing us to adapt their instructions and bring these amazing strips to our community!
