The publication describes a simplified method of evaluation of basic parameters of the fractionation process in the gravity field of three- and four-component biological mixtures having physical parame-ters similar to peripheral blood. The description of the method contains the balance of masses and forc-es imposing independent movement of microparticles of different shape in the base fluid matrix. It was also assumed that the biological mixture as an uncompressible quasi-homogeneous liquid can be de-scribed using the basic laws of hydrodynamics. The presented method of evaluation of basic parame-ters of the fractionation process, in relation to complex biological mixtures, together with calculation examples, is a prelude to the extended peripheral blood test within the sedimentation rate of erythro-cytes OB (ESR). Keywords: fractionation of biological mixtures, sedimentation of blood components, mixture fractionation process model, a peripheral blood OB test, fractionation in the gravity field.
