A Comprehensive Metabolic Panel (CMP) is a blood test that measures various substances in the blood to assess overall health. It typically includes tests for glucose, calcium, electrolytes, and proteins, providing information about the body's metabolism, kidney function, and liver function. The CMP helps healthcare providers diagnose conditions such as diabetes, liver disease, and kidney disorders. It is often ordered during routine check-ups or when a patient shows symptoms that require further investigation. Regular monitoring through a CMP can help track changes in health over time.
