What condition is indicated by an elevated white blood cell count?

An elevated white blood cell count is referred to as leukocytosis. This condition often indicates an underlying issue, such as an infection, inflammation, or stress response. White blood cells are key components of the immune system, and their numbers increase in response to various stimuli, signaling that the body is fighting off infection or other stressors.

Leukopenia, on the other hand, indicates a reduced white blood cell count, which would suggest a compromised immune response. Anemia relates to a deficiency in red blood cells or hemoglobin, impacting oxygen transport rather than white blood cell counts. Hypernatremia refers to an elevated sodium level in the blood, which is unrelated to white blood cell counts.
