Ethical approval: This study was approved by the Ethical Committee of University of Palermo (protocol: 07/2019). This work uses data obtained by healthy volunteer subjects (research staff and volunteer medical students) collected at the Dept of BiND and DISB, University of Palermo and Urbino, respectively, as part of their care and healthy bio-humoral checks. All investigations have been conducted according to the Declaration of Helsinki principles. In line with non-interventional retrospective design of this in vitro study, investigations were performed on volunteers without clinical indications and no clinical decisions were made based on measured values.
