Essais de standardisation d’un test de pression de filtration des éléments figurés du sang et application à I’agrégation plaquettaire

The authors describe the standardization of a new technique for studying, based on the filtration pressure exerted by x aggregates on a given filter. First results concern the study of the filtration pressure of whole blood, platelet-enriched plasma and the effect of ADP on concentrations ranging from 0.1 to 100/ml. The filtration pressure of PRP increases with the dose of ADP used. Biological and clinical applications of the method are considered both for aggregates of cells and for substances preventing aggregation.
