Which of the following is NOT typically involved in a complete blood count (CBC)?

The correct answer is C, as the blood glucose level is not part of a complete blood count (CBC). A CBC primarily assesses different components of blood to provide information about the patient's overall health and detect a variety of disorders, such as anemia, infection, and many other diseases.

A CBC typically includes measurements of hemoglobin, which indicates the oxygen-carrying capacity of blood; platelet count, which is crucial for understanding the blood's ability to clot; and white blood cell count, which helps in evaluating the immune response and identifying infections or hematological conditions.

In contrast, measuring blood glucose levels is associated with a different set of tests, often included in metabolic panels or diabetes screening rather than a CBC. Therefore, while the other components are integral to the CBC, the blood glucose level stands apart, confirming that option C is the one that does not belong in this grouping.
