Method and equipment for measuring platelet aggregation and blood coagulation factor

Abstract

The invention relates to a method for measuring the platelet aggregation and a blood coagulation factor. In the method, a full-automatic coagulate blood analytical instrument is used, the platelet aggregation is measured by using photoelectric turbidimetry and the blood coagulation factor is measured by using a double magnetic circuit and bead method. The method comprises the following measuring steps of: preparing a platelet aggregation inductive agent, platelet rich plasma and platelet poor plasma; respectively reading light transmittance data of a platelet poor plasma sample and light transmittance data of a platelet rich plasma sample as well as light transmittance data of the platelet rich plasma during the forming process of the platelet aggregation within the specified time; calculating the platelet aggregation rate of the measured blood sample; absorbing the platelet poor plasma and injecting the platelet poor plasma in a hemagglutination cup; absorbing the selected reagent according to a test program and injecting the selected reagent into the hemagglutination cup; automatically monitoring the amplitude of a steel bead; and generating a test report by using measuring results of the platelet aggregation and the blood coagulation factor according to input information of patients.

Problems solved by technology

However, the test method of this patent has major defects. Only one blood sample can be measured at a time, which belongs to the category of manual measurement, which will not only prolong the test time, but also affect the accuracy of the test results due to manual negligence. Personnel contamination due to direct contact with patient blood samples
