The Centers for Disease Control and Prevention (CDC) has developed Traceable Opioid Material® Kits (TOM Kits®) to support laboratory detection of current and emerging opioids as well as common co-drugs found in fentanyl-containing samples. The following TOM Kits® are available from Cayman free-of-charge to qualified labs.
The Fentanyl Analog Screening (FAS) Kit and emergent panels (FAS V1-V4) contain reference standards that enable labs to screen 250 synthetic opioid compounds, including more than 210 fentanyl analogs. The FAS and FAS V1-V4 Kits are no longer available.
The Emergent Drug Panel (EDP) and EDP-V1 Kits expand coverage to co-drugs that may be found in fentanyl-containing samples. The EDP and EDP-V1 provide coverage of 80 emergent synthetic opioids, benzodiazepines, stimulants, hallucinogens, synthetic cannabinoids, and xylazine.
The Emergent Drug Panel - Internal Standard (EDP-IS) Kit contains isotopically labeled versions of select compounds included in the EDP and FAS Kits for use as internal standards in mass spectrometry-based analyses.
