About Blood Viscosity

Cardiovascular disease is not only the number one killer of adults, but is associated with a host of chronic conditions that impact the quality of life.  With an aging population, accurate, early detection of risk factors that increase the likelihood of heart attack, stroke, and related conditions is essential.  Meridian Valley Lab is pleased to be an innovator in this field, offering the only commercially-available multi-point blood viscosity test.  In
addition, MVL offers testing for a wide array of cardiovascular risk markers.

Blood is a non-Newtonian fluid with a viscosity that changes with velocity.  Blood flowing fast (such as at systole) is less viscous than slower flowing blood (diastole).  Blood viscosity at diastole is anywhere from 2-1/2 to six times higher than blood at systole.  Viscous blood is abrasive and damages blood vessel walls, contributing to the initiation of the atherosclerotic process.  Whole blood viscosity assessment is most useful when both diastolic and systolic viscosity are measured.
