According to Smoluchowski aggregation, the kinetics of colloids is based on the assumption that each particle is surrounded by a "sphere influence". Single spherical particles which undergo Brownian motion collide and sticking of particles happens. As aggregation proceeds, the average diffusion constant of the aggregate population decreases. The aggregation of red blood cells progresses in the same manner except that cells are biconcave rather than spherical. WebAug 1, 2014 · When rouleaux is suspected, phenotyping may be done with washed RBCs and a saline-replacement technique can be used for tests involving direct agglutination. 31 Rouleaux is not observable in antiglobulin test results because the washing phase that is performed before adding the antiglobulin reagent typically removes the plasma proteins …
