Quality control experimental method for full-automatic platelet aggregation instrument

Abstract

The invention relates to a quality control experimental method for a full-automatic platelet aggregation instrument. In the method, simulated biological blood plasma is taken as quality control substance stock solution, and an experiment is performed according to photoelectric turbidimetry. The experiment comprises the following steps of: diluting the quality control substance stock solution by using distilled water in a ratio, and preparing a low-concentration quality control substance and a high-concentration quality control substance respectively; commanding a sample loading needle to absorb the low-concentration quality control substance and inject the absorbed low-concentration quality control substance into the test cup of a machine core test device, wherein the machine core test device automatically reads the transmittance data of the low-concentration quality control substance; commanding the sample loading needle to absorb the high-concentration quality control substance froma sample disk device according to detection standard quantity and inject the absorbed high-concentration quality control substance into the test cup of the machine core test device, wherein the machine core test device automatically reads the transmittance data of the high-concentration quality control substance; calculating and outputting a mean value, a standard difference and a transmittance difference value according to the transmittance data; and determining the stability of the full-automatic platelet aggregation instrument according to an experimental result.

Description

technical field [0001] The invention relates to a quality control experiment method of a fully automatic platelet aggregation instrument. The method uses a fully automatic platelet aggregation instrument, uses simulated biological plasma as a stock solution of a quality control substance, conducts experiments according to photoelectric turbidimetry, and is used to determine automatic platelet aggregation. Stability of aggregator performance. Background technique [0002] In the prior art, there are many methods for measuring platelet aggregation and many influencing factors, so there is no ideal open quality control substance as a standard for external quality control. Therefore, if each laboratory uses the detection system of the same manufacturer, including the platelet aggregation meter and the quality control substance of the platelet aggregation meter, regular comparisons can be made to ensure that the detection system is in good working condition. According to the lit...
