Strategy of analysis for reticulocyte count by FC/TO and CD61PE A) selection of the population of interest, R1, based on morphometric aspects for the construction of graph B (FL1 × anti-CD61PE/FL2); B) identification of the homogeneous population, R2, and possible interferents - R3 and R4; C) quantification of the percentage of positive cells in the upper right quadrant (stained with TO) present in the R2 region - graph drawn with the combination of gates in R1 and R2 regions. FC/TO: method of reticulocyte count by flow cytometry, using thiazole orange; SSC: side scatter; FSC: forward scatter.
