The differentiated erythrocyte sedimentation rate

Summary The author has studied Erythrocyte Sedimentation Rates in the open air and in a copper container. All blood samples were obtained, every time, from the same subject. The results of the experiments, which lasted from May to September 1957, show a significant effect of the copper shield. The present article is the continuation of the studies published by the author in the Int. Journ. of Biocl. and Biomet. vol I, part IV, section C 1, 1957.
