Embodiment 1

[0033] The method for improving the stability of the platelet aggregation index of the present invention uses a platelet aggregation index detection device to measure according to photoelectric turbidimetry, and the determination steps are:

[0034] A. Use a blood collection test tube to collect a patient's blood sample (according to the detection standard dosage, usually 5ml), and carry out anticoagulant treatment on the blood sample to generate anticoagulant whole blood; centrifuge the anticoagulant whole blood to prepare a platelet-rich plasma sample and The platelet-poor plasma sample; the platelet-rich plasma sample is stored in the platelet-rich plasma sample cup of the sample disk device, and the sample number is set; the platelet-poor plasma sample is stored in the platelet-poor plasma sample cup of the sample disk device, and the sample number is set; this embodiment In the process, the patient's blood sample is anticoagulated with blood anticoagulant 3.8% (concentrati...

Embodiment 2

[0042] This embodiment is an improvement made on the basis of Embodiment 1. For the same content in this embodiment as Embodiment 1, please refer to the content disclosed in Embodiment 1 for understanding, and no repeated description is made here; the disclosure in Embodiment 1 The content should also be taken as the content disclosed in this embodiment.

[0043] see Figure 3-Figure 6 , the method for platelet aggregation index stability of the present invention, uses a kind of full-automatic platelet aggregation instrument, measures according to photoelectric turbidimetry, and determination step is:

[0044] A. Use the blood collection test tube to collect the blood sample of the patient, perform anticoagulant treatment on the blood sample to generate anticoagulant whole blood; start the centrifuge device to centrifuge the anticoagulant whole blood, and the centrifuge will separate the platelet-rich plasma at the first gear speed, command The sampling needle or the automati...

Abstract

The invention relates to a method for improving stability of a platelet aggregation index; the method comprises the steps: determining according to a photoelectric turbidimetry; making a patient blood sample into a platelet-rich plasma sample and a platelet-poor plasma sample; transferring the platelet-poor plasma sample into a test cup, automatically reading light transmittance data of the platelet-poor plasma sample by a detection optical path system, and storing in a microcomputer; transferring the platelet-rich plasma sample into the same test cup, automatically reading light transmittance data of the platelet-rich plasma sample by the detection optical path system, and storing in the microcomputer; injecting a platelet aggregating agent into the same test cup, automatically reading data of the light transmittance of the platelet-rich plasma sample changing along with the time in a regulated time by the detection optical path system, storing in the microcomputer, and calculating out the platelet aggregation index by the microcomputer according to a formula; and generating a test report from the determination results of the platelet aggregation index according to inputted patient information.

Description

technical field [0001] The invention relates to a method for improving the stability of platelet aggregation index. The method is used for the determination of clinical platelet aggregation rate; the measurement is carried out according to the photoelectric turbidimetry, the PPP sample is moved into the test cup, and the light transmittance data is read by the detection optical path system; Move the PRP sample into the same test cup, and read the light transmittance data with the detection optical system; inject the platelet aggregation agent into the same test cup, and read the data with the detection optical system. Background technique [0002] Chinese patent 200910083611.6 discloses a method for measuring platelet aggregation. An automatic platelet aggregation instrument is used for measurement based on photoelectric turbidimetry. The measurement steps are: preparing platelet aggregation inducer, prepared platelet-rich plasma and platelet-poor plasma Place it in the samp...
