The hematology analyzer allows the measurement of several hematological parameters useful in diagnostic and clinical patients. In leukemia, hematological parameters especially in the case of leukocyte differential count helps early diagnosis of leukemia.
A cross sectional study in 57 subjects. Measurement of differential count using two hematology analyzers Yumizen H1500/2500 and Sysmex XN-1000. The statistical tests were Mann-Whitney and Spearman’s test. The test results are significant if the p-value < 0.001.
57 patients consisted of 15 AML, 12 ALL, 14 CML, 9 MDS, and 7 other diagnosis. There was significant relationship between the leukocyte differential count parameter with the morphology of peripheral blood smear and bone marrow aspiration (p<0,001). The correlation between leukocyte differential counts parameters of two hematology analyzers using Spearman’s correlation has a significant positive correlation with moderate to very strong (p<0,001). The parameters of leukocytes, lymphocytes, and eosinophils were very strong correlation (r = 0,990, 0,892 and 0,717), monocytes and neutrophils were a strong correlation (r = 0,706 and 0,782) and basophils were moderate correlation (r = 0,376).

b. Blood smear patient with CML c. Bone marrow smear patient with CML
The results of the leukocyte differential count showed the same cell types found in the morphology of the peripheral blood smear and bone marrow aspiration. The correlation between the two hematology analyzers showed that the results of the differential count were either increasing or decreasing even though the methods of the two hematology analyzers were different.
There was no difference in the leukocyte differential count parameters between both hematology analyzers and had a significant positive correlation with the morphology of the peripheral blood smear and bone marrow aspiration.
