Which test is a part of the routine CBC (complete blood count)?

The test that is a part of the routine complete blood count (CBC) is the hemoglobin test. A CBC is a comprehensive blood test that measures various components of blood, including red blood cells, white blood cells, hemoglobin, hematocrit, and platelets.

Hemoglobin is crucial for assessing the oxygen-carrying capacity of the blood, and it provides essential information regarding a patient's overall health and potential anemias. The measurement of hemoglobin is integral to the CBC, as it helps in diagnosing conditions like anemia, polycythemia, and other hematological abnormalities.

While a platelet count is also part of a CBC, hemoglobin specifically represents the amount of hemoglobin protein in the blood, which is a key parameter evaluated routinely. Prothrombin time and fibrinogen assays, however, are not part of the standard CBC; they are tests related more specifically to coagulation and the clotting process rather than to the routine evaluation of blood cell counts and their respective components.
