Abrégé

The present invention relates to an in-vitro method for detecting anti-erythrocyte antibodies in a sample, comprising at least the following steps: a) bringing the sample into contact with one or more test erythrocytes or a suspension of one or more test erythrocytes having a known phenotype, under conditions likely to induce hemagglutination, so as to obtain a reaction mixture; b) bringing the reaction mixture into contact with a solid substrate containing a plurality of defined adsorption areas which have previously fixed antibodies or antibody fragments capable of binding antigenic determinants present on the one or more test erythrocytes; c) ascertaining the presence or absence of a hemagglutination reaction in at least one of the adsorption areas so as to detect the presence or absence of anti-erythrocyte antibodies in the sample; the steps a) and b) being carried out separately or simultaneously.
