Title:
METHOD AND DEVICE FOR IDENTIFYING PLATELET AGGREGATION, AND CELL ANALYZER
Document Type and Number:
WIPO Patent Application WO/2018/232589
Kind Code:
A1
Abstract:
The present invention falls within the field of medical apparatuses. Disclosed are a method and device for identifying a platelet aggregation, and a flow cytometer, which are used for accurately giving an alarm about a platelet aggregation during blood cell analysis. The method comprises: detecting a pre-treated blood sample by using a flow cytometry technique so as to acquire a scattered light signal and a fluorescent light signal of the blood sample, wherein the scattered light signal is a forward scattered light signal or a sideward scattered light signal; differentiating between a blood stain and a white blood cell by using a fluorescent light-scattered light scatter plot formed by the scattered light signal and the fluorescent light signal of the blood sample; and counting the number of particles in a blood stain feature region in the fluorescent light-scattered light scatter plot of the blood sample and determining whether the number of particles exceeds a threshold value, and if the number of particles exceeds the threshold value, giving a platelet aggregation alarm.
