| Abstract: | A report is presented on the results of investigations made in 188 657 prospective blood donors from 1974-1980 within the district of Magdeburg. Methods of investigation and recommendations of the International Society of Blood Transfusion for selecting blood donors are compared. A total of 12337 (= 6.53%) were not admitted as a donor and 1360 blood conserves (0.77%) could not be used for transfusion because of laboratory findings obtained afterwards. Causes are dealt with in detail. The necessity of supervising the health of donors and the existing limitations for it are pointed out. |
