[Preventive-medicine screening methods in the examination of blood donors].

From a blood transfusion service with ca. 7000 donors a year, there was a loss of donors whose blood, having undergone medical tests, was found to be unsuitable. Details of all such donors were carefully documented. The results were ascertained by attentive control of the health of the donors which, in part, exceeded the minimum requirements laid down by the existing regulations. The relatively high loss of donors and the kind of disease underline the importance of these control checks, as an aspect of preventive medicine. This is of particular importance with regard to the results of so-called "new donors", who register for the first time. They had to undergo examination, and were only allowed to give blood when all the results of the tests had been submitted. The question then arises as to whether the regulations for the differing minimum requirements for the examination of "occasional donors" and "regular donors" can be maintained. A reduction of the expenditure on the present regulation examination of donors is not advocated because of both responsibility towards the blood donors, and in view of the increasing significance, to the medical care of patients, of the proximity of a clinic to an expedient transfusion service.
