Figure 1From: Performance evaluation of the Pima™ point-of-care CD4 analyser using capillary blood sampling in field tests in South AfricaDaily 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.Back to article page
