The objective of this study was to investigate the utility of finger-prick blood samples for CD4 cell counting. We estimated agreement between CD4 cell counts in paired finger-prick and venous samples from 110 HIV-infected adults from Malawi. Bias was 6.6 cells/microl (limits of agreement -50.7 and 63.7 cells/microl) for absolute counts and 0.71% (limits of agreement -2.07 and 3.48%) for %CD4/lymphocyte suggesting that finger-prick blood samples can be used interchangeably with venous samples for CD4 cell counting.
