A Complete Blood Count (CBC) shows anemia by measuring specific parameters related to red blood cells.
According to the reference provided, a CBC for anemia specifically assesses:
- Hematocrit: The amount of red blood cells in the blood.
- Hemoglobin: The level of hemoglobin in the blood.
These two measurements are key indicators of anemia.
Here's a breakdown of why these are important:
- Hematocrit: A lower than normal hematocrit indicates a decreased volume of red blood cells in the blood, which is a sign of anemia.
- Hemoglobin: Hemoglobin is the protein in red blood cells that carries oxygen. A low hemoglobin level means there isn't enough oxygen being transported to the body's tissues, indicating anemia.
To further clarify, consider this table:
| Measurement | What It Measures | Low Levels Indicate |
|---|---|---|
| Hematocrit | Volume of red blood cells | Reduced red blood cell count, a sign of anemia. |
| Hemoglobin | Oxygen-carrying protein in red blood cells | Reduced oxygen carrying capacity, a sign of anemia. |
In summary, a CBC identifies anemia through decreased levels of hematocrit and hemoglobin, which directly reflect the reduced amount of red blood cells or their oxygen-carrying capacity.
