Exploration of Feasability of Blood and Saliva Proteomic Analysis Through Harvesting by Silica Matrix (NanoDx-CoV-19) (NanoDxCoV19)
Exploration of Feasability of Blood and Saliva Proteomic Analysis Through Harvesting by Silica Matrix
Phase 1:
25 patients with a PCR-based diagnosis of Covid-19 will be be included to give 500 microliters of saliva and a 3 ml sample of blood for proteomic analysis; a drop of blood will also be put in a device connected to a silica matrix to perform spectrometric analyses. 25 patients with a non-Covid-19 respiratory infection will be included for the same samples. The proteomic analyses will be performed from classicaly draught blood, blood drop on silica, and saliva, to search for discriminating profiles between Covid-19 and non-Covid-19.
Phase 2:
150 patients with a suspected Covid-19 will be included at the same time than the Covid-19PCR is performed ; they will have a sample of saliva and of a drop of blood for proteomic analysis, whose results will be matched with PCR results.
