Increase in the number of circulating white blood cells.
any condition in which the number of leukocytes or white cells in the circulating blood is abnormally high; a white cell count of 10,000 or more per cubic millimeter. This is a non-specific finding. Generally when there is an increase in red cell production, the white cell count is elevated. If there are many immature red blood cells present in the circulation, the white cell count as done by a machine is elevated. A 'corrected white count' is then done manually with a microscope.[close window
Leukocytosis is an increased number of WBCs. It is usually caused by an increase in the number of circulating neutrophils (neutrophilia), though lymphocytosis (especially with leukemia) occasionally produces leukocytosis. Absolute values of individual WBC types provide much more diagnostic specificity than a simple WBC count. Exercise, fear and digestion cause physiologic leukocytosis. Infection, rapidly growing neoplasms, acute hemolysis, hemorrhage, intoxication, leukemia and trauma cause pathologic leukocytosis.
(loo-ko-sigh-toe-sis) : having more than the usual number of white blood cells.
an increase in the number of white blood cells, characteristic of many infections and other disorders
an abnormal increase in the number of white blood cells in the blood as a result of infection (as in leukemia)
An abnormally large number of leukocytes in the blood, which can be indicative of acute infection.
An abnormally high number of leukocytes in circulation. This condition can occur during acute infection, inflammation, hemorrhage, and other conditions. Generally, a cell count greater than 10,000 cells/mm³ indicates leukocytosis.
abnormally high number of white blood cells.
an increased white blood cell count, usually caused by the presence of an infection.
An increased number of white blood cells in circulation
Increase in total white blood cell count.
A temporary increase in the number of white blood cells circulating in blood.
An increase in the number of leukocytes in the blood.
An abnormally high number of leukocytes in the blood. This condition can occur during many types of infection and inflammation.
A condition characterized by an abnormally high total number of circulating leukocytes.
Abnormally high white blood cell count, usually the result of a non-viral infection.
An increase in the number of white blood cells in the circulating blood that occurs normally (as after meals), or abnormally (as in some infections).
Leukocytosis is an elevation of the white blood cell count (the leukocyte count) above the normal range. The normal adult human leukocyte count in peripheral blood is 4.4-10.8 x 103/L. A white blood count of 11.0 or more suggests leukocytosis.
