Define leukopenia.

Define leukopenia.

• A. A reduced number of red blood cells
• B. A condition with an excess of leukocytes
• C. A reduction in the number of white blood cells
• D. An increased level of platelets

Answer: (C)

Leukopenia is defined as a reduction in the number of white blood cells, which are crucial components of the immune system responsible for fighting off infections and diseases. A decrease in white blood cell count can lead to increased susceptibility to infections and may be caused by various factors including bone marrow disorders, autoimmune diseases, and certain medications or therapies. Understanding leukopenia in this context highlights its significance in hematological health, as a healthy white blood cell count is vital for maintaining the body's immune response. The other options do not pertain to white blood cells: a reduction in red blood cells refers to anemia, an excess of leukocytes describes leukocytosis, and an increased level of platelets relates to thrombocytosis. Each of these conditions has different implications for patient health, further emphasizing the unique definition and importance of leukopenia.
