As a result of change in regulations we have replaced some liquid reagents with crystalline ones. “Crystals” may not be intuitive for everyone at first, so we are publishing the following guide and instructional video.

To detect fentanyl or test for fentanyl analogs it’s recommended to use fentanyl test strips.
