The condition associated with an elevated white blood cell count is leukocytosis. This occurs when there is an increase in the number of white blood cells in the bloodstream, which can result from various factors like infections, inflammation, stress, or other medical conditions. A heightened white blood cell count is essentially a protective response, indicating that the body is fighting off an infection or dealing with another stressor.

Leukopenia, on the other hand, refers to a decreased white blood cell count, which can lead to increased susceptibility to infections. Thrombocytopenia relates to a low platelet count, which is not directly associated with white blood cell counts. Meanwhile, thrombocytosis pertains to an increased platelet count, which also does not imply an elevated white blood cell count. Therefore, the identification of leukocytosis as the condition characterized by elevated white blood cell counts is essential in understanding hematological responses to various physiological and pathological processes.
