E.S.R. Red Blood Cell Synthesis Speed Test

Abstract

The ESR (erythrocyte sedimentation rate) is a century old and common test for detecting acute and chronic inflammation. This test has served as a nonspecific indicator of presence of disease. It also has been found useful in monitoring response to therapy, especially in rheumatologic disease. It reflects both plasma concentration of acute-phase proteins of large molecular size and anaemia. The ESR test is easy to perform and inexpensive, is used today as a routine test worldwide. However, the ESR has some demerits, in requiring large volume of sodium citrate or EDTA blood and at least 1 hr testing time. The minimum of 1 hr testing time is not practical for modernized laboratories. Present study evaluates the process, background, levels and other associated components of ESR.
