# Viscosity

> This test measures the thickness of the fluid part of your blood to determine how easily it flows through your blood vessels. It helps show whether high levels of abnormal proteins are making your blood too thick, which can slow down circulation and cause symptoms like blurred vision or dizziness. This measurement assists doctors in evaluating hyperviscosity syndrome, a condition often linked to certain blood disorders or autoimmune diseases. However, this test does not identify the specific cause of the thickening or diagnose a specific disease on its own.
