85810 Blood viscosity examination
Also known as: Viscosity test, blood rheology study
Blood viscosity examination measures the resistance of blood flow, assessing plasma viscosity and red blood cell contribution to blood rheology in various pathological conditions.
In Plain Language
Blood thickness test; Flow resistance measurement
Clinical Context
Used in evaluating polycythemia, hyperviscosity syndromes (multiple myeloma, Waldenström macroglobulinemia), and conditions causing increased blood thickness affecting organ perfusion.
