Left Shift of Granulopoiesis with IG Flag


In this patient a clearly increased WBC count was found, accompanied by an IG flag. In all scatterplots the neutrophil cluster was more dispersed than normal, indicating increased heterogeneity of the neutrophil series. The size of most neutrophils was more or less normal but at the same time part of the neutrophils show larger size in combination with lower complexity. Looking at the lobularity it is also evident that the position of the neutrophil population on the 90 ° signal was lower than in a normal sample, indicating that most neutrophils tend to have a decreased lobularity.


This combination of results is typical of neutrophilia with more severe left shift.
