The erythrocyte sedimentation rate (ESR) test is a simple and inexpensive laboratory which measures the distance 
that erythrocytes have fallen after one hour in a vertical column of anticoagulated blood under the influence of gravity (aafp.org). Below we provide you with article about erythrocyte sedimentation rate in conjunctions with the interpretation in the clinical utility.
The article will describe you about the principle and performance of this ESR test, the importance and clinical utility of ESR, Methods of ESR measurement and factors affecting the ESR (in cleared and detailed table). In the clinical utility, the ESR test may give valuable informations for screening, diagnosis (Temporal Arteritis, Giant Cell Arteritis, Polymyalgia Rheumatica, Other Inflammatory Diseases) and monitoring disease activity ( Rheumatoid Arthritis, Neoplastic Diseases, Other Collagen Vascular Diseases) or therapeutic response, according to the article.
Another alternate ESR test methods such as Zeta Sedimentation Ratio (ZSR), VES-matic ESR, Micro-ESR, are also describe in this article.
