In the clinical laboratory, if abnormal white blood cells are suspected in the automatic blood cell analyzer, the flag is displayed and the technique is performed. Therefore, the technique for all specimens is difficult in reality to detect Immature cells or Abnormal cells. However, in the automatic blood analyzer, the sensitivity control of the flag is error in false negative and false positive samples, and the samples of specific diseases including the normal samples are also found to efficiently select and classify white blood cells. In this study, there is no collection of human origins, and the correlation between the retest rate and the total blood counting test result is analyzed as the result of the general blood test commissioned to the eone test center from 2017 to 2018 with 102 samples. The analysis showed that the average number of white blood cells was 13,300/μ_L, higher than normal. Cells corresponding to Neutrophil or Lymphocyte were reported as Immature cells or band neutrophils. We examined the correlation between the test results obtained through the blood analysis equipment and the results of the white blood cell differential calculation obtained through the manual. In the group analysis between these two groups, Neutrophil (P<0.001) and Lymphocyte (P<0.01) showed statistically significant correlations. In addition, the correlations between automation equipment and each white blood cell derived by handwriting showed a high correlation between Neutrophil (r=0.904), Eosinophil (r=0.994), and Lymphocyte (r=0.925). The results of the technique showed statistical significance between groups with differences in Leukocyte numbers: Neutrophil (P<0.001) and Lymphocyte (P<0.001) and Monocyte (P<0.05). After the test, the correlation between the Immature cell result value and the automation analysis result showed that Neutrophil was negatively correlated with Band, Metamyelocyte and positive correlation, blast and Atypical lymphocyte. Lymphocyte showed positive correlation between Band neutrophil, Metamyelocyte and negative correlation, and Atypical lymphocyte. Monocyte showed a positive correlation with Blast. Basophil showed positive correlation with Myelocyte and Atypical lymphocyte. This is presumed to be a result of the reports in the automation equipment, which may lead to errors in correlated cells. This study has a limitation point by performing some samples without any distinction between the retrospective part and the normal/abnormal sample. In conclusion, using flagging systems or scatters used in each laboratory to help quantitative reduction of the technique, it is possible to calculate the best results that can be trusted by using abnormal samples as a hand technique by refer to the Leukocyte discrimination pattern of the results of the complete blood counts.
