typing [tīp´ing]

in transplantation immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (such as those on leukocytes or erythrocytes) are detected by means of suitable isoimmune antisera.

blood typing (typing of blood) determining the character of the blood on the basis of agglutinogens in the erythrocytes; see also blood group.

phage typing characterization of bacteria, extending to strain differences, by demonstration of susceptibility to one or more races (a spectrum) of bacteriophage; widely applied to staphylococci, typhoid bacilli, and other organisms for epidemiological purposes.

tissue typing identification of the human leukocyte antigens of the donor and recipient of a transplant or transfusion; see also tissue typing.

typing

in transplantation and transfusion immunology, a method of measuring the degree of organ, solid tissue, or blood compatibility between two individuals, in which specific histocompatibility antigens (e.g. those present on leukocytes) or other cell surface antigens, e.g. red blood cell antigens, are detected by means of suitable immune serum.
