A preliminary comparative report of quantitative buffy coat and modified quantitative buffy coat with peripheral blood smear in malaria diagnosis.

The quantitative buffy coat (QBC) technique is a method of diagnosing malarial parasites based on micro-centrifugation, fluorescence, and density gradient of infected red blood cells. The aim of the present study was to modify the QBC technique in order to reduce the cost per test of malaria diagnosis. This was achieved by introducing some modifications to routine QBC wherein REMI centrifuge (cost Rs 19000/-) and ultra-violet microscope (Rs 115000) were used instead of parafuge (Rs 108000) and paralens (Rs 293625/-).
