ABSTRACT:
An apparatus for determining the filterability of red blood cells comprises a first upper transparent block containing at the center a capillary having an inner diameter between 1 and 10 mm, which block is provided with two level detectors; a second lower transparent block, provided with a central duct--facing the capillary of the upper block--inside which duct is housed a drop-taking device, such duct being connected on the one hand to a drain circuit and on the other to a pressure regulating circuit; a filtering membrane housed between the two blocks and a frame for holding the apparatus.First the initial mean flow time of the serum is measured, then the initial mean flow time of a volume of the suspension of cells in the plasma at a given concentration using such apparatus, and then the index of filterability is calculated.
