BLOOD ANALYSIS METHOD, CONTROL DEVICE, AND BLOOD CELL ANALYZER

摘要

The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.

主权项

1. A blood analysis method for a blood cell analyzer, the blood cell analyzer comprising a reaction cell where a testing sample is prepared from a blood sample, and a detection apparatus which detects the testing sample for leukocyte detection, and said method comprising:
injecting a blood sample and a first reagent into the reaction cell, wherein the first reagent lyses erythrocytes in the blood sample and reacts with leukocytes in the blood sample to obtain a first testing sample; transferring a part of the first testing sample from the reaction cell to the detection apparatus for leukocyte four-group classification detection; injecting a second reagent into the reaction cell after transferring the part of the first testing sample, wherein the second reagent reacts with leukocytes in a remainder of the first testing sample to obtain a second testing sample; and transferring the second testing sample to the detection apparatus for basophil classification detection.
