blood group (blud grldbomacp) 1. an erythrocytic allotype (or phenotype) defined by one or more cellular antigenic groupings controlled by allelic genes. Numerous blood group systems are now known, the most widely used in matching blood for transfusion being the ABO and Rh groups. 2. any of various other characteristics or traits of cellular or fluid components of blood, considered as the expression (phenotype or allotype) of the actions and interactions of dominant genes, and useful in medicolegal and other studies of human inheritance.
blood group, n classification based on the presence of certain antigens on the surface of red blood cells. Types include A, B, AB, O, and Rh+ or Rh−. Used in organ tranplantation, trans-fusion therapy, genetic studies, and maternal-fetal compatibility testing. blood group the phenotype of erythrocytes defined by one or more cellular antigenic structural groupings under the control of allelic genes. The identification of specific blood groups is little used in veterinary medicine, except for the identification of parents, usually in horses and farm animals, and for purposes of selecting blood donors. For blood transfusions the usual practice is to carry out direct matching tests to avoid problems created by incompatibility. For blood group systems, see Table 7. |

| There are four ABO blood groups based on the presence or absence of two specific antigens--A and B--and two Rh blood groups. But this time researchers have gone against type, cloning the genes that determine two major blood groups, A and B. All the tests including EKG, treadmill, urinalysis, PSA, CBC, blood chemistry, lipid profile and blood group are done at Casa Velas in the privacy of the on-site Cardiologist's office. |
