WebA flow cytometry strategy that only uses the CD45-dim area with or without CD34 can underestimate or overestimate the number of blasts. Variability between the morphological and flow cytometric blast estimate exists due to sample hemodilution and to changes in the proportion of the populations due to sample processing (lysing and washes).
