| First separate edition. Robin Fåhræus introduced the erythrocyte sedimentation rate test. The above paper is Fåhræus' comprehensive description of the suspension stability of the blood. Suspension stability is the basis for measurements of the sedimentation rate. Originally published in Acta Medica Scandinavica, vol. 55 (1921), pp. 1-228. 45 text illustrations. Prior to the above full description of his work, Fåhræus published some of his observations in his first two papers on suspension stability; Om hämagglutinationen, särskilt med hänsyn till havandeskapet och möjligheten av att diagnostiskt utnyttjadensamma, published in Hygiea, vol. 80:7 (1918), and; Über die Ursachen der verminderten Suspensionsstabilitet der Blutkörperchen während der Schwangerschaft, published in Biochemische Zeitschrift, vol. 89:5-6 (1918). ESR (erythrocyte sedimentation rate) is a nonspecific screening test for various diseases. This 1-hour test measures the distance (in millimeters) that red blood cells settle in unclotted blood toward the bottom of a specially marked test tube. Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and a band or blood pressure cuff is placed around the upper arm to apply pressure and cause the veins below the band to fill with blood. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding. |
