Erythrocytosis

erythrocytosis /eryth·ro·cy·to·sis/ (-si-to´sis) increase in the total red cell mass secondary to any of a number of nonhematogenic systemic disorders in response to a known stimulus (secondary polycythemia), in contrast to primary polycythemia (polycythemia vera).

Erythrocytosis

Increased production of red blood cells.

erythrocytosis (rith´rōsītō´sis),

erythrocytosis stimulating factor

a lipid isolated from the plasma of anemic animals; distinct from erythropoietin, causes production of microcytes without increasing hemoglobin. Its role in disease is unknown.

stress erythrocytosis

an apparent polycythemia resulting from diminished plasma volume.
