Résumé
The ideal hematocrit is the hematocrit (hct) value resulting in the highest value of hct / viscosity (h/h) ratio and can thus be predicted from viscometric measurements with the use of equations such as Quemada's one which yield the determination of the bell-shaped curve of h/h as a function of hct. In a series of recent papers we applied this approach to various populations, using viscopetry at high shear rate (1000 s -1 ) [1]. However the shape of this curve is dependent on the shear rate, resulting in a right-shift in this top value when hct increase, as previously described by Nemeth et al [2].
