Blood draw or sample collection at a local center

A comprehensive metabolic panel (CMP) is a group of 14 blood tests that assesses glucose, electrolyte and fluid balance, kidney function, and liver function. It includes glucose, calcium, sodium, potassium, chloride, carbon dioxide, blood urea nitrogen, creatinine, albumin, total protein, alkaline phosphatase, ALT, AST, and total bilirubin. Clinicians order it for routine checkups, medication monitoring, and evaluation of fatigue, swelling, or abnormal liver findings.

• Glucose Blood sugar level.
• Calcium Mineral involved in nerve, muscle, and bone function.
• Sodium Main electrolyte for fluid balance.
• Potassium Electrolyte important for heart and muscle function.
• Chloride Electrolyte for fluid and acid-base balance.
• Carbon dioxide (bicarbonate) Marker of acid-base balance.
• Blood urea nitrogen (BUN) Waste product reflecting kidney function and hydration.
• Creatinine Muscle waste product used to estimate kidney filtration.
• Albumin Liver protein that helps maintain fluid balance.
• Total protein Combined measure of albumin and other blood proteins.
• Alkaline phosphatase (ALP) Enzyme related to liver and bile ducts.
• Alanine aminotransferase (ALT) Liver enzyme.
• Aspartate aminotransferase (AST) Enzyme found in liver and other tissues.
• Total bilirubin Pigment processed by the liver.

• People having a routine health assessment.
• Those monitored for kidney or liver function.
• Individuals taking medications that affect metabolism or organ function.
• People evaluated for fatigue, swelling, or jaundice.
• Anyone being screened for abnormal blood sugar.

• Fasting may be requested, often 8 to 12 hours, especially for glucose.
• Water is usually allowed.
• Ask whether to take usual medications.
• Avoid heavy alcohol and strenuous exercise before the draw.
• Follow specific instructions from the ordering provider.

Each component is compared with its reference range. Glucose reflects sugar handling; electrolytes and minerals reflect balance; BUN, creatinine, and albumin relate to kidney and nutritional status; and ALP, ALT, AST, and bilirubin reflect liver and bile function. Patterns across the panel are more informative than one value. Results are a screening tool, not a diagnosis. Discuss them with a healthcare provider.
