Description
The Comprehensive Metabolic Panel (CMP) is a blood test that provides a broad overview of your body’s chemical balance and metabolism. It measures 14 different substances in your blood to assess kidney and liver function, electrolyte and fluid balance, and blood sugar levels. Because these markers are closely tied to multiple body systems, the CMP is often used as part of a routine health check, to monitor chronic conditions, or to help diagnose new health concerns.
What the CMP Measures
Kidney Function:
- BUN (Blood Urea Nitrogen) – Measures waste products in the blood to evaluate kidney health.
- Creatinine – Another key indicator of kidney function and waste filtration.
Liver Function:
- ALT (Alanine Aminotransferase) – Enzyme that rises with liver injury.
- AST (Aspartate Aminotransferase) – Enzyme involved in liver and muscle metabolism.
- Alkaline Phosphatase (ALP) – Can be elevated in liver or bone disorders.
- Total Bilirubin – Measures waste from red blood cell breakdown; high levels may signal liver or bile duct issues.
- Total Protein & Albumin – Reflect nutritional status and liver’s ability to make essential proteins.
Electrolytes & Fluid Balance:
- Sodium – Helps regulate fluid balance and nerve/muscle function.
- Potassium – Essential for muscle contractions and heart rhythm.
- Chloride – Helps maintain fluid balance and acid-base status.
- Carbon Dioxide (CO₂) – Reflects your body’s acid-base balance.
Blood Sugar:
- Glucose – Main source of energy for your cells; used to help detect diabetes and monitor blood sugar control.
Why This Test Is Important
- Monitors chronic health conditions like diabetes, liver disease, or kidney disease.
- Detects electrolyte imbalances that can cause fatigue, confusion, muscle weakness, or heart rhythm problems.
- Helps identify early warning signs of metabolic disorders before symptoms appear.
- Provides a baseline for ongoing health tracking.
Fasting is not required.
