choose the terms that describe abnormal white blood cell counts.

□ leukopenia

□ leukocytosis

□ primary polycythemia

• Leukocytosis is a condition where white blood cell count is abnormally high.
• Primary polycythemia (also known as polycythemia vera) is a disorder related to abnormal red blood cell production, not white blood cells. So it does not describe abnormal white blood cell counts.
