Which of the following is NOT a component of the CBC test?

The correct answer is the blood glucose level, which is not a component of the Complete Blood Count (CBC) test. A CBC test is designed to provide information about the cellular components of blood, specifically focusing on components such as total white blood cell count, total red blood cell count, and white blood cell differential count.

The total white blood cell count measures the number of white blood cells in a volume of blood, which is crucial for assessing the immune response and identifying potential infections or hematologic disorders. Similarly, the total red blood cell count helps evaluate the number of red blood cells responsible for transporting oxygen throughout the body, which is vital for diagnosing anemia and other blood disorders. The white blood cell differential count further categorizes the different types of white blood cells, providing insights into various health conditions and the body’s response to disease.

In contrast, the blood glucose level pertains to the amount of glucose in the blood and is used to assess metabolic conditions, such as diabetes. Since it does not evaluate the cells or cellular components of blood, it falls outside the scope of a CBC test.
