👉 Haemagglutination is a biological process in which red blood cells, or erythrocytes, are produced from the blood. This can occur during the immune response to infections by releasing antigens (antibodies) that bind to the surface of the erythrocyte membrane, leading to their aggregation and release into the bloodstream. The resulting hemoglobin is then released into the circulation, where it binds to other proteins in the blood plasma, allowing for transport of oxygen-carrying
