[Evaluation of the amount of microaggregates in preserved blood].

The tensometric method of the estimation of microaggregates in the blood and its preparations was used. It was shown that the process of aggregation of blood formed elements was dependent on the preservative content, period of storage and individual features of the donor. The filtration rate of the soviet and foreign microfilters was found to depend upon the initial content of microaggregates in the blood. The employed tensometric method is sufficiently simple and enables the objective estimation of the amount of microaggregates to be made. It is recommended for employment in the blood transfusion service.
