Cell-mediated immunity (CMI) tests are used to diagnose (prior) infection by intracellular pathogens.

A logistical hurdle of CMI tests is the fact that living cells are needed and hence blood needs to be stimulated within hours from collection.

Supported by the Horizon2020 Research and Innovation program with academic and industrial partners from Wien, Oss, Leiden and Freiburg we therefore designed a liquid handling device (termed WOLF) to facilitate the logistics of CMI testing and enable blood stimulation directly at the point of blood collection.
