What is leukopenia?

Leukopenia is a condition characterized by a white blood cell count lower than the normal range in the blood. Specifically, it is defined as a white blood cell count below the normal range of 4,000 to 10,000 cells per cubic millimeter. Possible causes include: 1. Infections: Such as viral or bacterial infections, which can cause extensive consumption of white blood cells during the fight against pathogens. 2. Medication effects: Certain medications, such as chemotherapy drugs and nonsteroidal anti-inflammatory drugs, may suppress white blood cell production. 3. Underlying diseases: Conditions such as aplastic anemia and systemic lupus erythematosus may directly affect the production and consumption of white blood cells. For leukopenia, appropriate treatment measures are typically required, including discontinuation of relevant medications, treatment of the underlying disease, and administration of white blood cell-increasing medications.
