Figure 2

External quality assessment using retrospective AFREQAS samples. Figure to show performance of Pima™ analysers using panels of retrospective SA-NHLS AFREQAS stabilized blood samples to establish external quality assessment of testing. In (A) performance of four Pima™ analysers - Pima™ analysers #2 and #3 were subsequently used for field testing in Phase II and in (B) during Phase III, the SA-NHLS Predicate (SA-NHLS Polokwane using PLG/CD4 - performance is noted together with performance of three independent Pima™ analysers field tested using pipette-filled cartridges on site. See details in text. Red circles define acceptable limits of ± 2 SDI and the green circle represents ideal performance (SDI = 0). Actual performance of the respective laboratory/clinic is shown in blue.
