What does a Comprehensive Metabolic Panel (CMP) include that a Basic Metabolic Panel (BMP) does not?

The Comprehensive Metabolic Panel (CMP) includes additional tests that provide more extensive information about a patient's metabolic state compared to the Basic Metabolic Panel (BMP). One key component of the CMP that is not part of the BMP is albumin levels. Albumin is a protein produced by the liver that plays a crucial role in maintaining oncotic pressure and transporting various substances in the blood. Its measurement can provide insights into liver function, kidney health, and nutritional status.

While the BMP assesses elements that primarily reflect kidney function and electrolyte balance—such as glucose, calcium, sodium, potassium, carbon dioxide, and chloride—it does not include albumin levels. This makes albumin an important marker only available through the CMP, thereby enhancing the overall diagnostic capability of that panel for evaluating a patient's health status.
