A Comprehensive Metabolic Panel (CMP) is a broad screening test which is used to evaluate organ function and electrolyte balance as well as aid in the diagnosis of conditions such as diabetes, liver disease, and kidney disease. This test is also useful for monitoring people receiving treatment for conditions which affect the liver or kidneys. The CMP contains all of the measurements in a Basic Metabolic Panel and most of the same measurements as a Hepatic Function Panel and a Renal Function Panel.
A CMP includes the following tests:
Glucose: Abnormal blood sugar levels can indicate a number of conditions including Diabetes.
BUN (Blood Urea Nitrogen): Used to evaluate kidney function.
Creatinine: Used to Evaluate Kidney Function.
BUN/Creatinine Ratio: This measurement can indicate kidney disease or conditions such as dehydration or intestinal bleeding.
Estimated Glomerular Filtration Rate (eGFR): Used to screen for and detect early kidney damage.
Sodium, Potassium, Chloride, Carbon Dioxide, Total: An improper electrolyte balance can indicate a number of conditions including dehydration, Addison's disease, kidney disease, and Diabetes.
Calcium: Normal levels are important for healthy bones, heart, nerves, kidneys, and teeth.
Protein, Total: Aids in measuring Liver and Kidney function as well as nutritional status.
Albumin: A protein important for health liver and kidney function.
Globulin: A protein that helps the body fight infection and the blood to clot properly.
Albumin/Globulin Ratio: Can help identify various liver problems when combined with other test results.
Bilirubin, Total: Helps to identify conditions such as anemia , sickle cell, hepatitis, cirrhosis, alcohol and drug abuse.
Alkaline Phosphatase (ALP): Used to detect liver disease or bone disorders.
Aspartate Amino Transferase (AST): Used to evaluate liver function, very high levels often indicate Hepatitis
Alanine Amino Transferase (ALT): Used to help identify liver damage.
A CMP is usually ordered as part of a routine health check. It may also be ordered when someone is experiencing symptoms which may indicate conditions affecting the liver or kidneys.
