What is erythrocyte sedimentation rate? First, you need to understand what erythrocyte sedimentation rate is. Erythrocyte sedimentation rate, also known as erythrocyte sedimentation rate, is a measure of the free sedimentation rate of red blood cells in the blood. Under normal circumstances, red blood cells in the blood do not settle to the bottom quickly, but when there is inflammation or other infections in the body, the red blood cells in the blood gather together and settle to the bottom, causing the blood sedimentation rate to rise. Elevated erythrocyte sedimentation rate may be related to cardiovascular disease, rheumatoid arthritis, liver disease and other diseases.
