Comprehensive Metabolic Panel

Components of the CMP

The CMP generally includes 14 individual tests, which can be grouped as follows:

1. Electrolytes and Fluid Balance:
   • Sodium: Helps regulate fluid balance and is essential for nerve and muscle function.
   • Potassium: Critical for heart and muscle function.
   • Chloride: Works with other electrolytes to regulate blood pressure and fluid balance.
   • Carbon dioxide (Bicarbonate): Maintains the body’s acid-base (pH) balance.
2. Kidney Function:
   • Blood Urea Nitrogen (BUN): Waste product filtered by the kidneys; high levels may indicate kidney dysfunction.
   • Creatinine: Waste product of muscle metabolism; elevated levels suggest kidney issues.
3. Blood Sugar (Glucose):
   • Glucose: Primary source of energy; high or low levels may indicate diabetes or other metabolic disorders.
4. Proteins:
   • Albumin: Major protein made by the liver, crucial for maintaining fluid balance.
   • Total Protein: Measures the overall level of protein in the blood, including albumin and other proteins that help fight infection.
5. Liver Function:
   • Alanine Aminotransferase (ALT): Enzyme found in the liver; high levels indicate liver damage.
   • Aspartate Aminotransferase (AST): Enzyme in the liver and muscles; elevated levels suggest liver or muscle damage.
   • Alkaline Phosphatase (ALP): Enzyme related to bile ducts; high levels may indicate liver or bone disease.
   • Bilirubin: Waste product from the breakdown of red blood cells; elevated levels may suggest liver or bile duct issues.

Why is the CMP Important?

The CMP is valuable for diagnosing and managing various conditions, such as:

• Kidney Disease
• Liver Disease
• Diabetes
• Electrolyte Imbalance

Preparing for the CMP

Fasting for 8–12 hours before the test is often recommended to avoid affecting glucose levels.
