Final answer:
A blood bank technology specialist performs tests on blood samples, types the blood, tests for diseases, and determines medical problems.
Step-by-step explanation:
A blood bank technology specialist is trained to perform routine and special tests on blood samples from blood banks or transfusion centers.
This specialist measures the pH of blood, types it (according to the blood's ABO+/- type, Rh factors, and other typing schemes), tests it for the presence or absence of various diseases, and uses the blood to determine if a patient has any of several medical problems, such as anemia.
A blood bank technology specialist may also interview and prepare donors to give blood and may actually collect the blood donation.
