Which of the following is NOT a component of a comprehensive metabolic panel (CMP)?

A comprehensive metabolic panel (CMP) is a group of blood tests that provide important information about the body's chemical balance and metabolism. The CMP typically includes measurements of glucose, electrolytes, protein, and liver enzymes, among other components.

The white blood cell count is not part of a CMP; instead, it is included in a complete blood count (CBC). The CMP is focused primarily on metabolic processes and organ function, particularly the liver and kidneys, while the CBC is more concerned with the body's immune status and overall hematologic health. This distinction clarifies why the white blood cell count is not included in the CMP, making it the correct answer to the question regarding which component is not part of this metabolic panel.
