Figure 1

Daily quality control. Figure to show excellent reproducibility using stabilized whole blood quality control material, i.e., IM "normal" and IM "low" across both predicate (PLG/CD4) and four Pima™ analysers during laboratory testing in Phase I. Statistically significant differences (Student's t-test, p < 0.05) between predicate and Pima™ CD4 counts, shown in the figure, reflect tight precision-to-predicate demonstrated in the %SIM analysis. No statistical differences were, however, noted between individual Pima™ analysers when testing either IM normal or IM low material (one-way ANOVA, p > 0.05). Performance using external quality control material is shown in Figure 2.
