Erythrocyte sedimentation in mediums with a low osmolality under a strong magnetic field

Abstract

Erythrocyte sedimentation rates (ESR) at a low osmolality just below hemolysis have been measured under a strong magnetic field. ESR of spherocyte in plasma solution was significantly greater than that in saline solution. The magnetic field, however, did not enhanced ESR. It was concluded that the major determinant can work only for anisotropic erythrocytes and is a magnetic field induced increase in an inter-membrane adhesive area due to magnetic orientation of anisotropic erythrocytes.
