Fentanyl Analog Screening Kit (FAS Kit) and Emergent Panels

The FAS Kit and its three additional emergent panels (FAS V1, FAS V2, and FAS V3) contain reference materials that support laboratory screening for 212 synthetic opioids, including over 190 fentanyl analogs.

These materials are distributed by Cayman Chemicalexternal icon, an ISO-accredited reference material producer, to labs located in the US and its territories. Labs eligible to apply for the FAS Kit and its emergent panels must have a valid DEA controlled substance registrationexternal icon for Schedule I controlled substances.

TOM Kits* are reference materials and do not eliminate the need to meet analytical method requirements of other federal agencies or the need to comply with respective state and local regulations. TOM Kits* are not for diagnostic use.
