[Trial routine dections of malaria. Experimentation of 1,500 blood donors].

The aim of our research was to look for specific malaria antibodies in a randomized sample of 1.500 blood donors. We used the indirect immunofluorescence technique. During this project we have noticed the lack of validity of the "the five years rule" usually followed in France to prevent transfusion malaria. We have also evaluated the help brought by an "oriented investigation" allowing firstly a selection of potentially dangerous donors, secondly, the use of their blood bottles according to serology results. This work finally shows that total security can only be achieved by systematic research on all blood donors.
