Platelet counting method and system

Abstract

The invention discloses a blood platelet counting method and system. The method comprises the steps that within certain testing time, a laser counter is used for testing a blood platelet test sample to acquire a blood platelet signal data set in each fixed time period within the testing time, wherein each blood platelet signal data set comprises a plurality of original data; the original data in each blood platelet signal data set is subjected to fitting processing to acquire a plurality of blood platelet statistics values, and each blood platelet statistics value corresponds to the corresponding blood platelet signal data set; the effective value range is calculated according to the average value of the blood platelet statistics values; the blood platelet statistics values exceeding the effective value range in the blood platelet statistics values are deleted, and the blood platelet counting result is calculated according to at least one left blood platelet statistics value. According to the method, it can be guaranteed that a testing result has high accuracy and stability.

Description

technical field [0001] The invention relates to the technical field of medical data processing, in particular to a platelet counting method and system. Background technique [0002] Platelet (blood platelet, PLT for short) is one of the formed components in mammalian blood. Irregular in shape, much smaller than red blood cells and white blood cells, no nucleus, platelets have specific morphological structure and biochemical composition, and have a relatively constant number in normal blood (for example, the number of human platelets is 100,000 to 300,000 per cubic millimeter), It plays an important role in physiological and pathological processes such as hemostasis, wound healing, inflammatory response, thrombosis, and organ transplant rejection. [0003] Platelet count refers to counting the number of platelets in a unit volume of blood. A normal platelet count is 100 x 10 9 / L~300×10 9 / L. When the platelet count is <50×10 9 / L, mild injury can cause skin and muco...

Problems solved by technology

[0004] It is a commonly used test method to detect the number of platelets by using the electrical impedance method through a hematology analyzer. The existing technology uses all the original data of the platelet signal to form a set of valid data for calculation within a test time. However, due to the platelet has Due to the physiological characteristics of easy adhesion and aggregation and the counting principle of blood cell analyzers, platelet counts are easily interfered by factors such as small red blood cells, cell debris, some particles similar in size to platelets, and counting time, so the data obtained by the test often fluctuate abnormally , abnormal data appear, which affects the accuracy and stability of the test results
