CPT Assistant guide: Coronavirus (SARS-CoV-2); August 2020 Antiglobulin testing, also known as the Coombs test, is an immunology laboratory procedure used to detect the presence of antibodies against circulating red blood cells (RBCs) in the body, which then induce hemolysis. After cells grown on cover glass are fixed and permeabilized, a primary antibody is added to detect specific antigen, and the secondary antibody conjugated to fluorescence tag (eg, FITC) is sequentially added to bind to the primary antibody. Whole blood collected by fingerstick will be tested immediately. The destruction of these red blood cells (RBCs) by antibodies directed against them is described diagnostically as autoimmune hemolytic anemia … Antiglobulin testing, also known as the Coombs test, is an immunology laboratory procedure used to detect the presence of antibodies against circulating red blood cells (RBCs) in the body, which then induce hemolysis.
