Whole blood ATP pools pre- and post-infusion The mean pre-infusion and immediate post-infusion whole blood ATP concentrations, in patients for whom this parameter was measured at weeks 1, 3, and 8 (N = 15 in week 1, N = 11 in week 3, N = 6 in week 8). A one-way ANOVA analysis for these data showed a significant difference in pre- and post-infusion whole blood ATP concentrations (p = 0.0099)
