The ESR is helpful in revealing inflammatory activity and in monitoring the progress of conditions associated with acute and chronic inflammation including infections, cancers, and autoimmune diseases.  The ESR is particularly useful in evaluating patients with unexplained symptoms, when infectious diseases are suspected, and when a specific diagnosis is not available using other tests. 

The ESR provides particularly valuable information in conditions such as temporal arteritis, polymyalgia rheumatica, giant cells arteritis, inflammatory arthropathies, etc. It may be used to follow the progress of the diseased state, or monitor the effectiveness of treatment.
