On the 14, 20 and 26 March 2024, the monitoring team of the oncNGS consortium conducted three site visits on the premises (laboratory) of the oncNGS phase 2 contractors. The three site visits took place in Waldbronn, Germany for Agilent Technologies Belgium; in Leuven, Belgium for  KU Leuven; and in Vienna, Austria for ViennaLab Diagnostics, as part of the Hufiat Cancer Liquidation consortium formed by Euformatics Oy (lead tenderer), Oncompas Medicine, and ViennaLab Diagnostics. We were especially glad and interested by the exchanges we had with them about the work they are performing. The members of the oncNGS monitoring team who performed the site visits were: Gordana Raicevic, Aline Hebrant, Hélène Antoine-Poirel (SCIENSANO); Luca Mazzarella, Gianmaria Frigè, Patrizio Giacomini (ALLEANZA CONTRO IL CANCRO); Maud Kamal, Nicolas Servant (INSTITUT CURIE); Olga Blau (CHARITE – UNIVERSITAETSMEDIZIN BERLIN); and Claude Van Campenhout (INSTITUT JULES BORDET).
