Which statement about the Comprehensive Metabolic Panel (CMP) is correct?

• A. It is identical to a Basic Metabolic Panel
• B. It includes only liver enzymes
• C. It includes BMP plus liver function tests
• D. It excludes electrolyte measurements

Answer: (C)

A Comprehensive Metabolic Panel combines a Basic Metabolic Panel with liver function tests, giving a broader view of metabolism, electrolytes, kidney function, and liver health. The BMP portion covers electrolytes (sodium, potassium, chloride, bicarbonate), kidney function (creatinine, BUN), and glucose. The CMP adds liver-related measurements such as liver enzymes and proteins (for example, ALT, AST, alkaline phosphatase, bilirubin, albumin, and total protein). That combination is why the statement is correct: it represents BMP components plus liver function tests. The other ideas don’t fit because the CMP is not identical to the BMP—it includes more tests beyond what a BMP offers. It does not contain only liver enzymes; it adds liver function tests to the BMP, not just those enzymes alone. And it does not exclude electrolytes; electrolytes are still part of the CMP.
