Which condition is most commonly diagnosed using a comprehensive metabolic panel?

A comprehensive metabolic panel (CMP) is a blood test that provides key information about an individual's metabolic state, including the levels of glucose, calcium, electrolytes, and kidney and liver function tests. One of its primary uses is to assess renal function, which is critical for diagnosing renal impairment. The CMP includes specific markers, such as blood urea nitrogen (BUN) and creatinine, that provide important insights into how well the kidneys are functioning and whether there is any indication of kidney dysfunction or disease.

While heart disease, diabetes, and respiratory failure can also be evaluated through various tests, they are not primarily diagnosed using a CMP. Heart disease diagnosis typically involves lipid panels, electrocardiograms, and other imaging techniques. Diabetes is primarily diagnosed with glucose testing and HbA1c levels. Respiratory failure assessment often relies on arterial blood gases and pulmonary function tests. Therefore, the renal impairment focus of the CMP makes it the most relevant choice among the options provided.
