CF plasma increases the reactivity of normal and CF platelets to ADP and TRAP. (A) Monocyte- and neutrophil-platelet aggregates in normal control whole blood incubated with CF plasma or ABO/RhD-matched normal plasma and then stimulated with agonist. (B) Monocyte- and neutrophil-platelet aggregates in CF whole blood incubated with CF plasma or ABO/RhD-matched normal plasma and then stimulated with agonist. Data are mean ± SEM; n = 6. ^*P < .05 versus normal plasma. ⁺P < .01 versus normal plasma.
