A CBC (Complete Blood Count) in thalassemia trait is a blood test that includes measurements of hemoglobin levels, red blood cell quantity, and red blood cell size, which helps identify characteristics associated with the condition. People with thalassemia trait typically have fewer healthy red blood cells and less hemoglobin than normal and their red blood cells may be smaller than normal.
Here’s a breakdown:
- Hemoglobin: This measures the amount of oxygen-carrying protein in your red blood cells. In thalassemia trait, hemoglobin levels are often lower than normal.
- Red Blood Cell Count: This indicates the number of red blood cells in your blood. Individuals with thalassemia trait may have a lower red blood cell count.
- Red Blood Cell Size (MCV): This measures the average size of your red blood cells. People with thalassemia trait often have smaller-than-normal red blood cells (microcytosis).
A CBC can help detect thalassemia trait, but further testing, like hemoglobin electrophoresis, is usually needed to confirm the specific type of thalassemia.
