the sedimentation rate (sed rate) blood test measures how quickly red blood. ESR is marker of infection/inflammation in the body and increase in determined by other tests including blood tests, x-rays, ultra sound etc.
The SED rate is a nonspecific hematology test that shows inflammation. It is elevated in pregnancy and rhematoid arthritis. It is decreased in congestive heart failure, polycythemia and sickle cell anemia.
SED rate is a type of blood test that measures how far red blood cells fall in a test tube in one hour. The measurement indirectly correlates with the inflammatory levels of the immune system in the body.
Erythrocyte sedimentation rate if raised signifies an inflammation somewhere in the cells of the body. It is normal up to 13mm/hour in males and up to 20 in females.
