Red Cell Mass and Plasma Volume Measurements in Elderly Men and Women With Anemia

Stanford University5 enrolled

Overview

On the basis that the clinical consequences of seemingly trivial levels of anemia are surprisingly severe, this study investigates if hemoglobin concentration accurately represents the underlying red cell mass in elderly patients with unresolved anemia.

For the study, the routine clinical measurement of hemoglobin will be compared to true red cell mass and plasma volume in elderly patients with anemia.
