Abstract
Erythrocyte simulating particles, a preparation method therefor, and a quality control or calibrator containing the erythrocyte simulated particles. The method for preparing erythrocyte simulating particles includes: performing oxidization and fixation treatments on erythrocytes by using an erythrocyte treatment solution that has a pH of 5.0-9.0 and an osmotic pressure of 300-800 Osm/kg·HO, wherein the erythrocyte treatment solution contains at least one oxidization agent selected from halogen oxygen acid salts and at least one fixation agent selected from aldehydes or acids; and washing the erythrocytes treated by the erythrocyte treatment solution and suspending the same in a preservation solution. The described method uses an environmentally friendly halogen oxygen acid salt as an oxidant, to obtain erythrocyte simulating particles that can be stored stably for a long time and have properties similar to natural erythrocyte particles in an erythrocyte detection channel.
