RBC histogram 256 channel high resolution RBC histogram Main RBC population RBC doublets 256 channel high resolution RBC histogram display cell population data between 24 and 350 fl
PLT histogram and curve fitting A fitted curve accurately reflecting the collected data is displayed between 2 and 35 fl Raw data Fitted Curve displayed up to 35fl PLT histogram is based on 64 channels
PLT curve fitting The Platelet count is derived from the number of cells under the fitted curve beyond the 35fl display limit extending up to 70 fl Raw data Fitted Curve extend up to 70 fl to report very large PLT count
PLT curve fitting The curve fitting process allows more accurate counts when platelets of larger than 20 fl are present
