Abstract
Erythrocyte deformability (E.D.) was investigated by two filtration techniques: the Hanss’hemorheometer and the Cell Transit Time Analyzer (CTA) in elderly subjects and in subjects with liver diseases.
Unlike the hemorheometer, the CTA technique is in a position to analyze the deformability of each red cell passing through 5 µm pores of a polycarbonate filter (Oligopore) under a low hydrostatic pressure. Both methods showed that E.D. was lower in the elderly group and in the liver diseases group than in the control group. Another characteristic of the CTA is to detect a few fractions of less deformable red cells.
