Final answer:
A Complete Blood Count (CBC) includes tests for WBC (White Blood Cells), H&H (Hemoglobin and Hematocrit), and Platelets. It does not typically include Calcium levels or PT/INR testing.
Step-by-step explanation:
A Complete Blood Count (CBC) is a blood test that is commonly ordered to evaluate the overall health and detect a wide range of disorders, including anemia, infection, and leukemia. A CBC measures several components of your blood, including:
- WBC (White Blood Cells)
- H&H (Hemoglobin and Hematocrit)
- Platelets
The CBC includes tests for red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). White blood cells are crucial for the immune response. The test also assesses hemoglobin concentration, hematocrit levels, and platelet count. Notably, a CBC does not typically include tests for calcium levels or PT/INR. For example, calcium levels are often measured when there's a need to evaluate parathyroid function or when there are signs of kidney stones or bone disorders. PT/INR is generally requested to examine blood clotting function in patients taking anticoagulant medication or in conditions affecting coagulation.
