Erythrocyte Sedimentation Rate (Sed Rate) (ESR)


An Erythrocyte Sedimentation Rate (ESR) is also known as a Sedimentation Rate (sed rate). An ESR is a blood test used to look for inflammation and tissue destruction. An elevated ESR is considered non-specific meaning it is not used for a specific diagnosis, but may indicate the presence of an underlying inflammatory process. This may be why an ESR is frequently done in combination with other testing.

An ESR will be elevated with an acute infection or some type of physical trauma. An ESR is frequently elevated in inflammatory processes such as infections and in autoimmune diseases such as rheumatoid arthritis and in cancer. Remember, research is mounting describing Alzheimer’s disease as an inflammatory process. There are many pathways leading to an increase in inflammation.
