[Comparison of methods for determining erythrocyte deformability]. / Confronto fra metodiche per la determinazione della deformabilità eritrocitaria.

We have studied the erythrocyte deformability by means of the filtration technique proposed by Reid et al. and with the new technique proposed by Schmid-Schönbein et al. using a Filtrometer MF4. We have studied 50 healthy subjects (24 females and 26 males) aged 25-61 (mean age 34 years). Our results show that slope 80% (SL80) and minimal value (MV) represent the more reliable indexes given by Filtrometer MF4. This instrument gives an exhaustive and automated analysis of erythrocyte deformability. Its results allow us a more extensive knowledge of hemorheological behavior of red blood cells in very low flow conditions.
