im·mu·no·trans·fu·sion

(im'yū-nō-trans-fyū'zhŭn),
An indirect transfusion in which the donor is first immunized by means of injections of an antigen prepared from microorganisms isolated from the recipient; later, the donor's blood is collected, defibrinated, and then administered to the patient; the latter is then presumably passively immunized by means of antibody formed in the donor, for example, antibody that reacts with the microorganisms in the patient.
