Final answer:

Clotting time is not measured during a complete blood count (CBC). CBC typically includes packed cell volume, hemoglobin concentration, and platelet count, but not clotting time, which is part of different coagulation tests.

Step-by-step explanation:

The complete blood count (CBC) is a common blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection, and leukemia. Among the various components measured by a CBC, clotting time is not one of them. Instead, CBC typically includes:

  • Packed cell volume (PCV) or hematocrit, which is the volume percentage of erythrocytes in a sample of centrifuged blood.
  • Hemoglobin concentration, which is the amount of hemoglobin in a given volume of blood.
  • Platelet count, which is the number of platelets, important for blood clotting, present in the blood.

Clotting time is a measure of how long it takes for blood to clot and is not included in the CBC. It's part of coagulation tests that assess the blood's ability to clot properly.
