Embodiment Construction

[0005] The detection and analysis process of the method of the present invention is as follows: the prepared anticoagulated blood sample to be tested is kept at a constant temperature and fully mixed, and then the number of platelets in the secondary blood sample is detected. For comparison, if the difference between the two data is not more than 10% of the average value, then the average value is used as the benchmark value of the platelet value detected this time. However, if one of the data is greater than 10% of the average value, the blood sample should be tested again. If the result is close to any of the two previously detected data, that is, it does not exceed 10% of the average value of the two results, then the two The average value of the data is used as the benchmark value of this test. Subsequently, add the aggregation inducer to the blood sample at a ratio of 9:1 (blood: aggregation inducer), mix thoroughly, and count the number of platelets in the blood sample c...

Abstract

The invention provides an optimized automation-adaptable platelet aggregation function inspection and analysis method, and belongs to the field of clinical laboratory medicine. The method is an improvement and optimization of a platelet aggregation function inspection and analysis method using an automation counting method. The method is suitable for platelet aggregation function automatic analysis instruments using the counting method. According to the method, the number of platelets is inspected and recorded and an aggregation rate is calculated. A laboratory test result shows that the method is better in repeatability of the obtained result of platelet aggregation rate compared with a previous largest aggregation rate method.

Description

1. Technical field [0001] The present invention relates to an optimized platelet aggregation function detection process and analysis method that is optimized by automatically measuring the change in the number of platelets in a blood sample before and after aggregation, and automatically performing analysis and calculation based on the change data to obtain an evaluation of the platelet aggregation function of the tested blood sample. , belonging to the field of clinical laboratory medicine. 2. Background technology [0002] Platelet aggregation function (or aggregation rate) is an important function of platelets in blood and an important index for evaluating blood coagulation function. The existing detection method of platelet aggregation function is mainly by detecting the change of optical density (or light flux performance) in plasma (whole blood) before and after platelet aggregation in plasma or whole blood (abbreviation: optical method), or putting electrodes into the...
