The ranges (mean ± 2 SD) for different lots of the commercial controls available in different months are plotted. Y axis represents CD4 counts and X axis represents months of the range establishment. Blue bars indicate manufacturer’s ranges and purple bars indicate laboratory established ranges. The yellow triangle in the middle of each bar indicates mean values.
