What is a common symptom associated with elevated white blood cell count?

An elevated white blood cell count, known as leukocytosis, often indicates an underlying condition such as infection, inflammation, or malignancy. Fever is one of the most common symptoms associated with an elevated white blood cell count because it is part of the body’s immune response to combat infections. When the body detects pathogens, it activates the immune system, leading to an increase in white blood cell production. This surge in white blood activity can stimulate fever-producing substances, resulting in an elevated body temperature to help fight off infection.

While fatigue, weight loss, and joint pain can occur alongside various health conditions that might also elevate white blood cell counts, they are not directly correlated in the same way fever is when discussing immediate reactions to infections and inflammation.
