Viscosity details
What Viscosity shows
Serum viscosity measures how thick the liquid part of your blood is, compared with water. It mainly depends on the amount and type of proteins in the serum, especially large antibody proteins. The test is used when there is concern about hyperviscosity, which can cause symptoms such as headaches, blurred vision, dizziness or bleeding from the nose or gums. A higher result can point to very high levels of certain proteins, as seen in conditions such as Waldenstrom macroglobulinemia, multiple myeloma or some autoimmune diseases. A normal result is reassuring for this purpose. Results are interpreted alongside protein tests such as protein electrophoresis.
Tests that include Viscosity
High serum viscosity may be most commonly observed in patients with Waldenstrวm's macroglobulinemia and multiple myeloma. Patients with high viscosity may have capillary occlusion, stasis hypoxia, and acidosis.
