What condition involves a decrease in the white blood cell count?Multiple ChoiceLeukopeniaThrombopeniaThrombocytosisAnemiaLeukocytosis

1. Break Down the Problem

We need to identify the correct term that describes a condition characterized by a decrease in the white blood cell count (WBC).

2. Relevant Concepts

• Leukopenia: Defined as an abnormally low level of white blood cells (leukocytes) in the blood.
• Thrombopenia: Refers to a lower than normal number of platelets (thrombocytes) in the blood.
• Thrombocytosis: Indicates an increased number of platelets.
• Anemia: Refers to a lower than normal red blood cell count or hemoglobin.
• Leukocytosis: Represents an increased number of white blood cells.

3. Analysis and Detail

• Since the question specifically asks about a decrease in white blood cell count, we must eliminate options that do not fit this description:
  • Thrombopenia (low platelets) is not related to WBC.
  • Thrombocytosis (high platelets) does not apply here either.
  • Anemia refers to red blood cells, not white blood cells.
  • Leukocytosis indicates an increase in white blood cells, opposite to what we need.

4. Verify and Summarize

After reviewing the terms, the only option that corresponds to a decrease in white blood cell count is leukopenia.

Final Answer

Leukopenia
