Is there hyperviscosity in pre-eclampsia?

There are conflicting reports on blood viscosity and its determinants in pr e-eclampsia. We investigated the presence of hyperviscosity and its determi nants in 25 nulliparous, pre-eclamptic Jamaican women. An equal number of n on-pre-eclamptic, gestation-matched women served as controls. There was no statistically significant difference in whole blood, plasma and serum visco sities, as well as in their determinants, namely, haematocrit, fibrinogen, IgM and IgG concentrations between the pre-eclamptic and control groups. Th is suggests that hyperviscosity is not a feature of pre-eclampsia in this J amaican population.
