All units tested were from blood donors at the Blood Bank at Haukeland University Hospital. Fresh WB samples were acquired directly from blood bags (Fenwal, Inc., Lake Zurich, IL, USA). The haematocrit values were measured as the volume percentage (%) of red blood cells in blood, whereas the haemoglobin values are given in g/dL. The values represent the average for the ten donors in each group, without collagen stimulation. An overview of the composition of the groups containing reconstituted whole blood is given in Table I. Abbreviations: PLTi: impedance platelet count; SD: standard deviation; Hb: haemoglobin; Hct: haematocrit.
