Clinical Significance
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 effectively using other tests.
The ESR provides particularly valuable information in conditions such as temporal arteritis, polymyalgia rheumatica,
giant cells arteritis, inflammatory arthropathies etc.
and chronic inflammation, including infections, cancers, and autoimmune diseases.
