Abstract: Disclosed are a method for determining a platelet concentration of a blood sample, a hematology system (100) and a storage medium.

Abstract: An alarming method for a platelet aggregation sample can include providing a blood sample, preparing a first test sample from the blood sample under a first reaction condition, acquiring a test signal of the first test sample, and obtaining first platelet test data. The method can also include preparing a second test sample from the blood sample under a second reaction condition, acquiring a test signal of the second test sample, and obtaining second platelet test data. The method can further include obtaining an evaluation result based on the first platelet test data and the second platelet test data, determining whether the evaluation result meets a predetermined condition, and alarming that the blood sample may be the platelet aggregation sample if the evaluation result meets the predetermined condition. The second reaction condition may include a reaction condition for reducing the platelet aggregation degree of the blood sample.

Abstract: A blood cell analysis method and a blood cell analyzer are provided. In the method and analyzer, characteristic information of white blood cell fragments is obtained based on side scattered light information and fluorescence information, characteristic information of platelets is obtained based on forward scattered light information and fluorescence information and then a count value for the platelets is acquired based on the characteristic information of the platelets and the characteristic information of the white blood cell fragments. The present invention can avoid the influence of the white blood cell fragments on the platelet counting, thereby ensuring the accuracy of the platelet counting without increasing costs.

Abstract: A method for identifying fragmented red blood cells comprising: acquiring side scatter light signals and fluorescence signals of cell particles in a sample liquid; and distinguishing and identifying a fragmented red blood cell population from the cell particles according to the side scatter light signals and the fluorescence signals of the cell particles. The fragmented red blood cell population can be identified from the cell particles by processing and analyzing the side scatter light signals and fluorescence signals of the sample liquid. The present application further provides a device for identifying fragmented red blood cells, a blood cell analyzer and an analysis method. Fragmented red blood cells can be identified according to the fluorescence that characterizes a nucleic acid content in a cell particle and the side scatter light, thus reducing errors in identification and counting.
