Which condition is characterized by a low white blood cell count?

• A. Anemia
• B. Epilation
• C. Erythema
• D. Leukopenia

Answer: (D)

Low white blood cell count is called leukopenia. White blood cells defend the body against infections, so having fewer of them means a person is more susceptible to infections. A typical threshold for leukopenia is a white blood cell count below about 4,000 cells per microliter, though exact limits can vary by lab. Leukopenia can result from bone marrow suppression (such as chemotherapy), certain medications, autoimmune diseases, severe infections, or radiation exposure. Other terms refer to different conditions: anemia is a shortage of red blood cells, leading to fatigue and pallor; epilation is hair loss; erythema is skin redness. Knowing leukopenia helps emphasize infection control and safety in imaging settings, since these patients may need extra precautions to reduce infection risk.
