ABSTRACT OF THE DISCLOSURE: There are disclosed blood products for parenteral administration which are essentially free of immune- modulating components, and methods for their production. The absence of immune-modulating components is expressed by the lack or absence of down-modulation of Fc receptors in the membrane of leukocytes. The expression of the receptors for the Fc fragment of immunoglobulin G in the membrane of monocytes, after interaction with a blood product preparation, is to be reduced not at all or by 30 % at most. The blood products are obtained - by molecular sieving of the blood products by gel permeation chromatography (gel filtration), or - by treatment of the blood products with a molecular sieve-like carrier material on which immune- modulating components are selectively adsorbed, or - by filtration of the blood products through filters having pore diameters of equal to, or smaller than, 10 nm.
