Medical Technologist double checks status on a unit of blood
prepared for transfusion to a patient.
Medical technologists in immunohematology screen and identify
the blood types of donor and recipient (patient) blood specimens
in preparation for blood and blood component therapy. Once
compatibility (cross-match) between donor and recipient has been
determined and tests for infectious disease are negative, the
blood may be transfused. Immunohematology also includes the
assessment for tissue compatibility which is necessary for
transplantation. An interesting technique is apheresis:
withdrawal of a patient's blood, treatment of the blood, and its
return to the patient. This procedure is often safer for the
patient than treatment of the whole body.
