  • Publication number: 20190226952
    Abstract: Methods of agglutinating and separating erythrocytes, by which erythrocytes can be instantaneously agglutinated into a sufficient size in a blood sample and completely separated from the blood sample; and a hemagglutination reagent are provided. The method of agglutinating erythrocytes according to the present invention includes adding a solution containing a cholic acid-based surfactant and an acid to a blood sample. The method of separating erythrocytes according to the present invention includes separating the erythrocytes agglutinated by the above-described method of the present invention. The hemagglutination reagent according to the present invention contains a cholic acid-based surfactant and an acid.
