associated CD4 count plotted as the dependent variable on the Y-axis. Six
PointCare NOW™ flow-cytometer/hematology devices tested 1,454 healthy
and immunocompromised persons with CD4% ranging from 5% to 75% in
sub-Saharan Africa. A color code was used to identify the associated absolute
lymphocyte count as low (<1,200 lymphocytes/microliter light blue, 10% of
samples), mid-normal (1,800 – 2,200 lymphocytes/microliter green, 28% of
samples) or high (>3,700 lymphocytes/microliter red, 4% of samples).
