  1. Data shown correspond to the mean values for 153 CBC results from malaria positive patients, obtained with a CD 3000 instrument in Lambaréné, Gabon. *Coloured pixels indicate the events that represent analysed cells in the side-scatter/depolarized side-scatter plot (lobularity/granularity) on-screen (Figure 1). ** % data lost = 1- (Mean number pixels on screen/Mean cell count in CBC result) × 100. Screen images were analysed by taking a screenshot and counting the pixels using ImageJ image processing software.
