Dataset Summary

Title	Benchmarking blood collection tubes and processing intervals for extracellular vesicle performance metrics
Description	Extracellular vesicle (EV) analysis from blood samples is under intense investigation and holds the potential to deliver clinically meaningful biomarkers for health and disease. Technical variation must be minimized to confidently assess EV-associated biomarkers but the impact of pre-analytics on EV characteristics in blood samples remains minimally explored. We present the results from the first large-scale EV Blood Benchmarking (EVBB) study in which we systematically compared 11 blood collection tubes (BCT; 6 preserving and 5 non-preserving) and 3 blood processing intervals (BPI; 1h, 8h and 72h) on defined performance metrics (n=9). The EVBB study identifies a significant impact of multiple BCT and BPI on a diverse set of metrics reflecting blood sample quality, ex-vivo generation of blood-cell derived EV, EV recovery and EV-associated molecular signatures. The results assist the informed selection of the optimal BCT and BPI for EV analysis. The proposed metrics serve as a platform to guide future research on EV pre-analytics and further support methodological standardization of EV studies.
