Stability Study of Fifteen Synthetic Cannabinoids of Aminoalkylindole Type in Whole Blood, Stored in Vacutainer® Evacuated Glass Tubes

The aim of this study was to evaluate the stability of blood concentrations of a variety of synthetic cannabinoids when spiked and stored in Vacutainer® evacuated glass tubes. Analysis for synthetic cannabinoids will be of less importance if the compounds disappear during transportation, and thus the previous must be tested for the specific tubes used during sample collection. In this study, tubes were filled with spiked whole blood and analysed after one week of storage at ambient temperature, in a refrigerator (+4°C), and in a freezer (-20°C).
