A Comprehensive Metabolic Panel (CMP) is a blood test that provides information about the body’s overall metabolic status and organ function. The CMP test measures various substances in the blood to evaluate the functioning of different organs and systems in the body. The test evaluates electrolytes, kidney function, liver function, blood glucose, calcium levels, protein levels, and cholesterol levels. A CMP is often ordered during routine health check-ups, for diagnosing certain medical conditions, monitoring ongoing medical conditions (like diabetes or kidney disease), or before surgery to assess your overall health and organ function. The results from a CMP help healthcare providers diagnose, monitor, and treat a variety of conditions related to metabolism, organ function, and electrolyte balance. Interpretation of results is typically done in conjunction with your medical history, physical examination, and other diagnostic tests.
