Research funding: The study population consisted of all patients undergoing routine laboratory testing at Lille University Hospital. Patients received detailed information that their clinical data and/or residual blood samples after routine testing had been completed could be used for research purposes. All data were retrieved from the human biological database previously authorized by the French Ministry of Research (No. DC-2008-642). Therefore, no written informed consent was needed for this study.
Employment or leadership: None declared.
