An increase in circulating leukocytes (white blood cells [WBC]).
Temporary increase in the number of white cells in the blood, typically, but not exclusively, caused by the presence of infection.
A slight increase in the numbers of white blood cells.
An abnormally large number of white blood cells, often brought about by acute infections.
Abnormal increase in the number of leukocytes in the blood; it frequently occurs as a result of infection, especially bacterial infection; a very large increase occurs in leukemia.
Increase in the actual number of leukocytes in the blood.
An increase of white blood cells in the circulation.
An increase in the number of white blood cells (leukocytes) in the blood.
An increase in the number of leukocytes (usually above 10,000/mm3) in the blood. It occurs most commonly in disease processes involving infection, inflammation, trauma, or stress, but it also can result occasionally from the use of some medications (e.g., corticosteroids).
Elevated levels of leukocytes in the bloodstream, a condition known as leukocytosis, are often observed during pregnancy and various infections and toxemias. Leukocytosis can serve as a diagnostic marker for inflammatory conditions, and the effectiveness of treatment can be assessed through daily leukocyte counts, which tend to decrease as the patient’s condition improves. This is a straightforward procedure for the patient, typically involving a blood sample collected from a minor finger prick.
