Apparatus for red blood cell separation
First Claim
1. Apparatus for separation of red blood cells from whole blood comprisinga cluster forming means comprising the combination of a primary filter through which plasma or serum can pass, and a mixture of a free agglutinating agent and a particle-associated agglutinating agent intimately associated with nucleating particles.

Abstract
Red blood cells are removed from whole blood or a fraction thereof by agglutinating whole blood with a mixture of a free agglutinating agent and nucleating particles having agglutinating agent intimately associated therewith to form clusters of red blood cells. High molecular weight polyethylene glycol may be added further to enhance agglutination. The clusters of red blood cells are much larger than the size of individual red blood cells, so that the clusters can easily be filtered through a porous medium. The plasma, which is substantially free of red blood cells, is further passed through a filter that optionally contains an additional agglutinating agent. Flow-delay additives may be provided to retain the fluid sample in contact with a reagent for a predetermined time.
