RESUMO
There are conflicting reports on blood viscosity and its determinants in pre-eclampsia. We investigated the presence of hyperviscosity and its determinants in 24 nulliparous, pre-eclamptic Jamaican women. An equal number of non-pre-eclamptic, gestation-matched women served as controls. There was no statistically significant difference in whole blood, plasma and serum viscosities, as well as their determinants, namely, haematocrit, fibrinogen, IgM and IgG concentrations between the pre-eclamptic and control groups. This suggests that hyperviscosity is not a feature of pre-eclampsia in this Jamaican population.

We measured plasma fibrinogen concentration (PFC), relative plasma viscocity (RPV), and arterial blood flow at the calf, ankle and great-toe in hypertensive and normotensive patients with diabetes compared with non-diabetic age and sex-matched control subjects. Blood flow after reactive hyperaemia at the ankle was also measured. PFC was measured by a clot-weight procedure. RPV was measured by capillary viscometery, and blood flow by venous occlusion plethysmography.
