Blood viscosity is a measure of the resistance of blood to flow. This test measures viscosity in serum and evaluates hyperviscosity syndrome (a group of symptoms triggered by increase in the viscosity of the blood). Hyperviscosity syndrome is associated with an increase in serum proteins or cells in conditions such as:

  • Waldenström macroglobulinemia
  • Mulitple myeloma
  • Leukemia (increased white blood cells)
  • Polycythemia (increased red blood cells)
  • Autoimmune disorders
  • Inflammation


Fasting is not required. Take all medications as prescribed.


This test does not measure whole blood viscosity, a measurement of the thickness and stickiness of an individual’s blood which contributes to the development of atherosclerotic plaques.
