Objective To analyze the test results of hematology analyzers in the automatic whole-blood mode and in the pre-dilution mode. Methods Mindray BC-5600 automatic hematology analyzer was applied for test of whole blood quality control materials for 30 times in the automatic whole-blood mode and the pre-dilution mode. Statistical analysis was conducted in the study. Results The test results and variation coefficients of white blood cell, red blood cell, hemoglobin, hematocrit and platelet in the automatic whole-blood mode were 7.3±0.07, 0.97; 4.97±0.03, 0.60; 130.0± 0.91, 0.70; 41.2±0.26, 0.63; 228.4±3.23, 1.41 respectively; and the test results and variation coefficients in the pre-dilution mode were 8.0±0.35, 4.38; 4.13±0.19, 4.60; 124.2±5.98, 4.81; 38.6±1.80, 4.66; 230.1±9.21, 4.00 respectively. The t value and P value for the five indicators were 10.74, 0.01; 7.57, 0.01; 5.43, 0.01; 7.83, 0.01; 0.95, 0.05 respectively. Conclusion Compared with the pre-dilution mode, the automatic whole-blood mode has smaller variation coefficient, higher precision and better repeatability.
