Abstract


Normoblast is an immature form of erythrocyte in erythropoietin system. Normally, normoblast can be found in peripheral blood
healthy neonates. The existence of normoblast in peripheral blood might be the sign of pathologic conditions such as hemolytic anemia,
acute blood loss, and ischemia and bone marrows abnormalities like malignancy or leukemia. In acute leukemia (Acute Myeloblastic
Leukemia and Acute Lymphoblastic Leukemia), normoblast existence in peripheral blood may due to erythropoietin system suppression.
The aim of this study is to compare normoblast count between AML and ALL, and also to find out the correlation between leukocyte and
normoblast count in AML and ALL. The subject of this study were patient diagnosed as AML (30) and ALL (30) in Hematology Division
of Clinical Pathology Department at Dr.Hasan Sadikin Hospital Bandung in July 2006–August 2008. In this study we examined 30
peripheral blood smears from AML and 30 peripheral blood smears from ALL. Leukocyte count result was derived from CBC performed
with Sysmex KX-21. The mean value of normoblast count from AML blood smear patients is 1930.60 (3.60/100 WBC) while ALL blood
smear patients is 309.60 (0.43/100 WBC). Statistically this difference is significant (p < 0.001). There are strong correlation between
leukocyte count and normoblast count within both group (r = 0.851, r = 0.948; p < 0.001).
