Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A blood analyzer, said blood analyzer comprising:
a reaction cell configured to prepare a first testing sample and a second testing sample from a blood sample;
a detection apparatus connecting with the reaction cell, and configured to perform a first detection of the first testing sample and a second detection of the second testing sample;
a sample injecting apparatus, which injects the blood sample into the reaction cell;
a reagent injecting apparatus, which injects a reagent into the reaction cell;
a transferring apparatus, which transfers the testing sample from the reaction cell to the detection apparatus;
a control device, which couples to the sample injecting apparatus, the reagent injecting apparatus and the transferring apparatus respectively;
wherein
the control device controls the sample injecting apparatus to inject a blood sample into the reaction cell, controls the reagent injecting apparatus to inject a first reagent for leukocyte classification into the reaction cell, wherein the first reagent lyses erythrocytes in the blood sample and reacts with leukocytes in the blood sample to obtain the first testing sample;
the control device controls the transferring apparatus to transfer a part of the first testing sample from the reaction cell to the detection apparatus for a leukocyte classification detection after said reaction between the blood sample and the first reagent is finished;
the control device controls the reagent injecting apparatus to inject a second reagent into the reaction cell having a remainder of the first testing sample after the part of the first testing sample is transferred, wherein the remainder of the first testing sample reacts with the second reagent which further reacts with leukocytes to obtain the second testing sample; and
the control device controls the transferring apparatus to transfer the second testing sample to the detection apparatus or a hemoglobin measurement apparatus after the leukocyte classification detection is finished.
