To the Editor I refer to some interesting data concerning the clinical significance of the results obtained with the TEST 1 instrument reported in the article by Cha et al,1 in which erythrocyte sedimentation rate (ESR) data obtained using the TEST 1 were compared with those obtained with the manual reference method according to the International Council for Standardization in Haematology.2 The...

BACKGROUND The erythrocyte sedimentation rate (ESR) is a simple and inexpensive laboratory test. It is commonly used to assess the acute phase response. METHODS A review of the recent literature was done to evaluate the role of the ESR and its importance in different clinical conditions both inflammatory and noninflammatory. RESULTS Despite the critical role cytokines have in inflammatory c...

The erythrocyte sedimentation rate (ESR) has become a ubiquitously used technique in medicine as a marker of systemic illness. The test involves placing anticoagulated whole blood into an upright test tube and monitoring the rate at which red blood cells (RBC) fall over time. Negative charges keep RBC from sticking together. If this charge is neutralised, RBC stack into chains, or rouleaux, and...

The Westergren method for the determination of the erythrocyte sedimentation rate has been conclusively shown to be more reliable than other methods (Gilmour and Sykes, 1951 ; Goldberg, Glynn, and Bywaters, 1952; Lewi and Clarke, 1954; Alexander and Andrews, 1957; Eastham, Denson, and Evans, 1958). Blood for a variety of haematological and biochemical investigations is commonly collected into W...

The aim of this work was to generate an inventory of the data on radiocarbon datings obtained from sediments of the São Paulo Bight (southern Brazilian upper margin) and to analyze the data in terms of Late Quaternary sedimentary processes and sedimentation rates. A total of 238 radiocarbon datings from materials collected using differents ampling procedures was considered for this work. The se...

Background. Erythrocyte sedimentation rate (ESR) is a valuable laboratory tool in evaluation of infectious, inflammatory, and malignant diseases. Red blood cells in outside from the body precipitate due to their higher density than the plasma. In this study we discuss the IVIG effect on ESR in different diseases and different ages. Methods and Materials. Fifty patients under 12 years old who ha...

The erythrocyte sedimentation rate (ESR) remains the most widely used laboratory test for monitoring the course of infections, inflammatory diseases, and some types of cancer. Several test methods have been developed recently, and as a result the safety and reliability of ESR testing procedures have improved. The method recommended by the International Council for Standardization in Haematology...

White blood cells, Erythrocyte sedimentation rate and C-reactive protein are sensitive tools to discover rare, but potentially serious pyogenic vertebral osteomyelitis, a disease whose incidence is increasing.

Mutants of Escherichia coti that fail to show the characteristic increase in permeability induced by brief treatment with ethylenediaminetetraacetate have been isolated. They were examined to see whether they release lipopolysaccharide as expected during such a treatment. Mutants derived from two strains released only 20 to 40% less lipopolysaccharide than their parents, but further analysis of...
