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