Understanding CBC Results in Leukemia: What to Expect

A complete blood count (CBC) measures red cells, white cells, platelets, hemoglobin, and hematocrit. In leukemia, typical findings include:

• Anemia: Low red cells → fatigue, weakness, pallor, shortness of breath.
• Leukocytosis: High white cells (may indicate infection or leukemia itself).
• Thrombocytopenia: Low platelets → easy bruising/bleeding.
• Blast cells: Immature white cells in peripheral blood—a hallmark of leukemia.

CBC is a key initial test, but bone marrow biopsy is usually needed for definitive diagnosis and classification.
