reticulocytosis

[rĕ-tik″u-lo-si-to´sis]

an excess of reticulocytes in the peripheral blood.

re·tic·u·lo·cy·to·sis

(re-tik'yū-lō-sī-tō'sis),

An increase in the number of circulating reticulocytes above the normal, which is less than 1% of the total number of red blood cells; it occurs during active blood regeneration (stimulation of red bone marrow) and in certain anemias, especially congenital hemolytic anemia.

reticulocytosis

[-sītō′sis]

an increase over the reference interval upper limit of 2.0% in the number of reticulocytes in the circulating blood that may represent a normal increase in activity of the bone marrow in response to blood loss.

reticulocytosis

A greater than normal proportion of RETICULOCYTES in the blood. This indicates an increased rate of red cell formation, as during the treatment of ANAEMIA or following HAEMORRHAGE.

reticulocytosis (rētik´ūlōsītō´-sis),

n an increase in the normal number of reticulocytes in the circulating blood. Normal values range from 0.5% to 1.5% of the red blood cells.

reticulocytosis

an excess of reticulocytes in the peripheral blood. See also reticulocyte response.
