Viscosity Blood Test (Labcorp)
This test measures blood viscosity. Viscosity is a measurement of the blood's resistance to flow. A simpler definition would be the thickness of the blood. Viscosity determines how well a person's blood flows through the veins which can affect how efficiently oxygen is transported to tissues and organs throughout the body as well as how much work is required by the heart to pump the blood. Viscosity is determined in part by the amount of hematocrit, red blood cells, white blood cells, and proteins in the blood. When blood viscosity increases it can cause a condition known as hyperviscosity. Symptoms of hyperviscosity include abnormal bleeding, headache, blurred vision, vertigo, chest pain, loss of coordination, seizures, and coma. Hyperviscosity is associated with a number of conditions including Waldenström macroglobulinemia, multiple myeloma, leukemia, polycythemia, rheumatoid arthritis, sickle cell anemia, and other autoimmune disorders.
A viscosity test may be ordered when a person has symptoms of hyperviscosity or has been diagnosed with a condition that is associated with hyperviscosity.
Turnaround for this test is typically 2-5 business days.
