About this test
The Comprehensive Metabolic Panel (CMP) is a widely used blood test that provides a broad overview of your metabolic health and organ function. It evaluates blood sugar levels, electrolyte and fluid balance, kidney function, and liver function—all key indicators of overall health.
By measuring 14 important biomarkers, the CMP helps identify early signs of conditions such as diabetes, kidney disease, liver disease, high blood pressure, and metabolic imbalances. It is commonly ordered as part of a routine physical exam, ongoing health monitoring, or to help investigate unexplained symptoms.
What Is Included In This Test?
The Comprehensive Metabolic Panel includes 14 individual measurements, along with several calculated values, to assess metabolism, kidney health, and liver function.
Blood Sugar and Metabolism
- Glucose: Measures blood sugar levels and helps screen for and monitor prediabetes and diabetes
Kidney Function
- Blood Urea Nitrogen (BUN): Measures waste from protein metabolism
- Creatinine with estimated GFR: Evaluates how efficiently the kidneys filter waste and excess fluid
- BUN/Creatinine Ratio (calculated): Helps assess kidney blood flow and function
Electrolytes and Fluid Balance
- Sodium: Helps regulate fluid balance and blood pressure
- Potassium: Supports heart rhythm, muscle, and nerve function
- Chloride: Helps maintain fluid and acid-base balance
- Carbon Dioxide (Bicarbonate): Helps evaluate acid-base balance
- Calcium: Supports bone health and kidney function
Liver Function and Proteins
- Albumin: A protein made by the liver that reflects liver health and nutritional status
- Total Protein: Measures albumin and globulins in the blood
- Globulin (calculated): Supports immune function
- Albumin/Globulin Ratio (calculated): Helps identify liver and immune-related conditions
- Alanine Aminotransferase (ALT): Liver enzyme that rises with liver damage
- Aspartate Aminotransferase (AST): Liver enzyme that may indicate liver injury
- Alkaline Phosphatase (ALP): Enzyme linked to liver and bile duct health
- Total Bilirubin: Measures waste processed by the liver; elevated levels may cause jaundice
Who Should Consider This Test?
The Comprehensive Metabolic Panel is appropriate for most adults and is one of the most commonly ordered lab tests.
You should consider a CMP if you:
- Want a comprehensive view of your overall health
- Are monitoring or screening for diabetes or blood sugar issues
- Have a history of kidney or liver disease
- Have high blood pressure or are at risk for metabolic conditions
- Take medications that may affect liver or kidney function
- Are experiencing symptoms such as fatigue, weakness, nausea, swelling, or unexplained weight changes
- Need baseline labs for preventive care or ongoing health monitoring
A CMP is a simple yet powerful test that helps detect health issues early and supports informed medical decisions.

What is the difference between a CMP and a BMP?
The CMP includes everything in a Basic Metabolic Panel (BMP) plus additional liver function tests and protein measurements. The BMP focuses mainly on kidney function, electrolytes, and glucose, while the CMP adds liver health.
Does the CMP test for diabetes?
The CMP includes a glucose test, which can help screen for and monitor diabetes. However, additional tests such as HbA1c may be needed for diagnosis or long-term glucose monitoring.
