Diagrammatic representation of blood pre-processing conditions employed in the current investigation. Fourteen separate experimental conditions (tubes of whole blood) were collected per subject. Processing consisted of centrifugation of whole blood and collection of plasma fraction for downstream biomarker measurement. Briefly, tubes selected for room temperature (RT) incubation were placed in racks within the laboratory at ambient temperature (22–23°C) for the allotted period of time. Tubes selected for 4°C incubation were placed within a laboratory refrigerator for the allotted time. The designated incubation periods were 4, 24 and 48 hours.
