Plasma Viscosity

Plasma viscosity estimation is a reflection of changes in plasma proteins within the blood. The values from normal subjects are within a narrowly defined range and change when protein fractions are altered. The major influence on plasma viscosity is exerted by fibrinogen and immunoglobulins. The Viscometer determines viscosity by measuring the resistance of the plasma flow through a capillary under a constant vacuum.
