When anticoagulated whole blood is allowed to stand, red blood cells settle out. The rate at which they fall is known as the erythrocyte sedimentation rate and is a rough measure of abnormal concentrations of acute phase proteins and immunoglobulins. This property makes ESR a sensitive, but nonspecific, indicator of tissue damage and inflammation.
Elevated ESR is an important diagnostic criterion for polymyalgia rheumatica and temporal arteritis, because these two diseases have few laboratory markers other than ESR elevation. ESR may be helpful in detecting occult disease. The most common causes of an elevated ESR in outpatients are infection, malignancy, and renal disease. The most common causes of extremely elevated ESR (>100 mm/hr) are infection, collagen vascular disease, metastatic cancer, and myeloma. ESR can be followed serially to monitor the course of a disease such as systemic lupus erythematosis or rheumatoid arthritis. ESR usually decreases within a few days after initiating corticosteroid therapy, but usually remains at a higher level than normal, even when the patient’s clinical status has dramatically improved.
Results from your sed rate test will be reported in the distance in millimeters (mm) that red blood cells have descended in one hour (hr). The normal range is 0-22 mm/hr for men and 0-29 mm/hr for women. The upper threshold for a normal sed rate value may vary somewhat from one medical practice to another.
