After platelet apheresis with Trima 7 and platelet additive solution substantial differences in cellular composition of LRS chamber products were observed. Leukocyte product was recovered from LRS chamber and total volume was determined (a). The cellular composition was analyzed, including white blood cell (b), lymphocytes (c), monocytes (d), red blood cells (e), neutrophils (f), eosinophils (g), basophils (h) and platelets (i) (n = 16 for Trima 6, n = 12 for Trima 7 and n = 20 for Trima 7 PAS; for (a) it is n = 13 for Trima 7 and n = 14 for Trima 7 PAS; statistical analyses were carried out using one-way ANOVA with Tukey test for multiple comparisons; effect size is reported as Cohen’s d).
