Comparing the AQUIOS CL PLG Application to the FC500 MCL FlowCARE PLG Application

The performance of the AQUIOS PLG System (or application) was assessed by comparing the results to the comparator estimation of difference as described in CLSI EP9-A3 Measurement Procedure Comparison and Bias Estimation Using Patient Samples; Approved Guideline, Third Edition. The comparator used FlowCARE PLG CD4 Reagent, ImmunoPrep Lysing reagent, and Flow-Count for CD4+ cell enumeration on FC 500 MCL flow cytometer with CXP software. The method comparison is comprised of HIV specimens from 38 pediatric and 202 adult subjects. The data provided in Table 1 and Figure 1 supports the premise that the systems are equivalent in their performance enumerating CD4+ lymphocytes in peripheral whole blood. Values are expressed in terms of percentage (%) of the total lymphocyte count and as absolute count (cells/µL) for total CD4+ cells.
