Simultaneous Use of I l3l -Albumin and Cr 51 -Labelled Red Cells in Blood Volume Studies in the Goat

Abstract

Summary

A method is described for determinations of cell and plasma volumes using Cr⁵¹ and I¹³¹ simultaneously in which hematocrit tubes are used for counting and separation of cells and plasma. In vitro determinations of volumes of blood were within 1% of actual volumes. Volumes and distributions found by this method in 4 goats are within the range of values found in the goat by other methods. Limitations of the method are also discussed.
