About Our Comprehensive Metabolic Panel (CMP)

The Comprehensive Metabolic Panel (CMP) measures blood sugar (glucose) levels, electrolyte and fluid balance, kidney function, and liver function.

The 14 measurements included in the CMP help to provide a look at the overall health of the body and its metabolism and chemical balance. The CMP is useful in helping to diagnose certain conditions like diabetes, kidney disease, liver disease and hypertension. The CMP aids in determining how the liver and kidneys are functioning and where glucose, calcium, protein, sodium, potassium, and chloride levels stand.


The CMP blood test measures levels of:

  • Albumin - Albumin is a protein made by the liver. Measuring levels of albumin is helpful in diagnosing liver disease. An albumin test measures how well your liver is making the proteins that your body needs.
  • Albumin/Globulin Ratio (calculated) - The A/G ratio is calculated from measured total protein, measured albumin, and calculated globulin (total protein - albumin) to help diagnose diseases.
  • Alanine aminotransferase (ALT) - ALT is an enzyme found predominantly in the cells of the liver. When the liver is damaged, ALT.
  • Alkaline Phosphatase - In conditions affecting the liver, damaged liver cells release increased amounts of ALP into the blood.
  • Aspartate aminotransferase (AST) - AST is a liver enzyme that is useful in helping to diagnose liver diseases.
  • Blood urea nitrogen (BUN) - Urea nitrogen is a byproduct from the breakdown of food proteins. A normal BUN level is between 7 and 20. As kidney function decreases, the BUN level rises.
  • BUN/Creatinine Ratio (calculated) - The ratio of BUN to creatinine (BUN:creatinine) is usually between 10:1 and 20:1. An increased ratio may be due to a condition that causes a decrease in the flow of blood to the kidneys.
  • Calcium - Measuring urine calcium can help determine whether the kidneys are excreting the proper amount of calcium and can also help diagnose kidney stones.
  • Carbon dioxide (Bicarbonate) - Your kidneys and lungs balance the levels of carbon dioxide, bicarbonate, and carbonic acid in the blood. Carbon dioxide levels can be used to help diagnose kidney disease.
  • Chloride - Chloride is an electrolyte. An increased level of blood chloride may indicate kidney disease.
  • Creatinine with estimated GFR - A waste product that comes from the normal wear and tear on muscles of the body. This test is a measure of how well the kidneys are removing wastes and excess fluid from the blood. The normal value for GFR is 90 or above, but may decrease with age. A GFR below 60 is a sign that the kidneys are not working properly. A GFR below 15 indicates kidney failure.
  • Globulin (calculated) - Globulin is a protein made in your liver and helps the immune system fight infections. Low globulin levels can be a sign of liver damage or other conditions.
  • Glucose - Levels of glucose in the urine indicate glycosuria. Renal glycosuria occurs when the renal tubules fail to reabsorb all glucose at a level that is normal.
  • Potassium - Potassium is an electrolyte. Kidney disease is the most common cause of high blood potassium.
  • Sodium - Sodium is an electrolyte. Abnormal levels of sodium help to determine if the kidneys are properly removing sodium from the body.
  • Total bilirubin - This test measure direct and indirect levels of bilirubin for a total bilirubin value. In cases of excess bilirubin, an obstruction, or an inflamed liver, the liver cannot process the bilirubin in the body because. When the body has too much bilirubin, your skin and the whites of your eyes will start to yellow causing a condition called jaundice.
  • Total protein - Total protein measurements can help diagnose liver diseases. Total Protein measures the amount of protein in your blood. The two main proteins found in the blood are globulins and albumin.
  • Alanine aminotransferase (ALT) - ALT is an enzyme found predominantly in the cells of the liver. When the liver is damaged, ALT levels are significantly elevated.
Fasting Instructions:

Fasting is required for the blood glucose test that is included in the CMP. Fasting is defined as no consumption of food or beverages other than water for at least 8 hours before testing.
