Abstract
In the midst of increase tendency of aged population, prevention of life-style-relating disorders is a great social concern. Chemistry and blood tests have been applied to find, prevent and control the disorders. One of common testing ways to detect the disorder is to use automated analyzers because of test simplicity and rapidity. CRP is commonly used for detect severity of acute inflammation. Erythrocyte sedimentation rate (ESR) is able to determine using whole blood anti-coagulated with EDTA in 10 minutes. The test will be one of best ways to find occult chronic disorders in the aged since many of reports revealed its clinical utility, different from CRP assay.
