Sedimentation Rate Test - More Information

The ESR test, also known as an erythrocyte sedimentation rate test or a sed rate by modified westergren blood test, checks the ESR blood level.

The ESR test is a test that analyzes how red blood cells (RBC) form a sediment over a sixty minute period. The blood test is used as a general measure of overall inflammation. During inflammatory processes, RBCs will stick to one another more readily and form dense stacks which from sediment more quickly.

Various clinical states of generalized inflammation will increase the ESR blood level. Some of these states, like pregnancy, are not related to an underlying illness. Other conditions like autoimmune disorders, cancers, and blood disorders will result in an elevated ESR. The ESR is still routinely helpful in diagnosing Kawasaki's disease and temporal arteritis. Additionally, ongoing measurement of blood ESR levels might be helpful in tracking the progress of inflammatory states in the body.
