APPLICATION OF THE RADIOACTIVE RED CELL METHOD FOR DETERMINATION OF BLOOD VOLUME IN HUMANS

Abstract
The application of radioactive red cells to detn. of human red cell mass is descr. and compared with simultaneous blue dye detns. The previously reported discrepancy between findings by dye methods and direct cell methods is confirmed. In a group of 28 <f patients in a variety of clinical states, great variability in the discrepancy between the 2 methods was observed. Until methods are more fully worked out, great caution should be exercised in estimating plasma vol. or cell vol. indirectly.
