CELL-DYN Ruby

Immature Granulocytes (IG)

Description

In contrast to the Granulocytosis cases, the granulocytosis in these two patients is characterised by distinctively abnormal neutrophil population cluster shapes. This cluster pattern is suggestive of immature granulocytes (IG), and this possibility is further indicated by the presence of IG/BAND flagging alerts. There are no other major abnormalities with regards to the WBC differentials although the increased monocyte and basophil counts in Case B may have relevance in the context of possible myeloproliferative disease. Both patients also show a moderate normocytic anaemia and mild to moderate reductions in the absolute platelet count. Reference microscopic review of these two samples revealed the presence of 19% IG in Case A and 16% IG in Case B.
