Which of the following best defines leukocytosis?

• A. A decrease in the white blood cell count
• B. An increase in the white blood cell count
• C. A normal white blood cell count
• D. An increase in red blood cell production

Answer: (B)

Leukocytosis is defined as an increase in the white blood cell count. This condition often occurs in response to a variety of factors, such as infections, inflammation, stress, or other medical conditions. When the body faces a challenge, such as fighting an infection, the bone marrow produces more white blood cells to help combat pathogens, leading to an elevated white blood cell count. A normal white blood cell count would indicate homeostasis in the immune system, whereas a decrease in the white blood cell count is referred to as leukopenia, which may suggest a compromised immune response or other health issues. The option regarding red blood cell production pertains to erythropoiesis, which is entirely separate from leukocytosis and focuses on red blood cell dynamics instead of white blood cells. Therefore, the most accurate definition of leukocytosis is an increase in the white blood cell count.
