1. A blood analysis method for a blood cell analyzer, the blood cell analyzer comprising a common reaction cell for classifying leukocytes where a first testing sample and a second testing sample are prepared from a same blood sample, and a detection apparatus which detects the first testing sample and the second testing sample, said method comprising:
when performing leukocyte five-group classification:
transferring a first aliquot of the blood sample to the common reaction cell;
delivering a first reagent into the common reaction cell, wherein the first reagent lyses erythrocytes and reacts with leukocytes in the blood sample to form the first testing sample;
transferring the first testing sample from the common reaction cell to the detection apparatus;
detecting the first testing sample in the detection apparatus for a first detection that classifies the leukocytes into lymphocyte group, monocyte group, neutrophil & basophil group and eosinophil group;
delivering a second reagent into the common reaction cell after the first testing sample is transferred for detection, wherein the second reagent shrinks leukocytes other than basophils to form the second testing sample;
transferring the second testing sample from the common reaction cell to the detection apparatus, and
detecting the second testing sample in the detection apparatus for a second detection that classifies the basophils.
