relative polycythemia

relative polycythemia
a decrease in plasma volume without the change in red blood cell mass of absolute polycythemia, so that the erythrocytes become more concentrated (elevated hematocrit). It occurs in both acute forms (a transient condition due to marked loss of body fluid, lowered fluid intake, or a combination) and chronic forms (see stress p.). Called also spurious p. and pseudopolycythemia.
