Comprehensive Metabolic Panel (14)
The Comprehensive Metabolic Panel (CMP) test checks your blood for 14 different substances. It checks the balance of chemicals in your body and your metabolism, which is how your body turns food into energy. CMP is used to check how well organs are working and find diseases like diabetes, liver disease, and kidney disease. The CMP may also be ordered to keep an eye on conditions like high blood pressure and to check on people who are taking medicine for any side effects that might affect the kidneys or liver.
A CMP checks your blood for the following things:
- Glucose: Glucose is a kind of sugar that gives your body and brain energy. Blood sugar is another name for glucose. High blood glucose when you wake up is often a sign of Type 2 diabetes. Having Type 1 diabetes is usually a sign of very high glucose levels, whether you are fasting or not.
- Calcium: Calcium is one of your body’s most important and most common minerals. Most of the calcium in your body is in your bones, but you also need calcium in your blood. Calcium in your blood is important for the health of your nerves, muscles, and heart.
- Total protein: This is a measurement of the total amount of proteins in your blood, including albumin and globulins.
- Bilirubin: This is a waste product made when red blood cells break down. It is up to your liver to get rid of bilirubin from your body.
- BUN (blood urea nitrogen): This is a measurement of urea nitrogen, which is a waste product that your kidneys help get rid of from your blood.
- Creatinine: This is a waste product made when your muscles work. It is a waste product that your kidneys take out of your blood by filtering it.
- Albumin: Your liver makes this protein. It moves important things through your bloodstream and keeps your blood vessels from leaking fluid.
A CMP also measures four electrolytes. Electrolytes are minerals that, when dissolved in a liquid, carry an electric charge. These electrolytes in your blood control how your nerves and muscles work. They also keep your blood’s acid-base balance (pH balance) and water balance in check.
- Sodium: Most of the sodium in your body comes from the food you eat. Your kidneys help control how much sodium is in your body.
- Potassium: You get potassium from the food you eat, and it is in all of your body’s tissues.
- Bicarbonate: The amount of carbon dioxide (CO2) in your blood is shown by the amount of bicarbonate in your blood.
- Chloride: Chloride works with sodium, potassium, and bicarbonate to control many of your body’s processes.
A CMP also checks for the three enzymes below in the liver. Enzymes are substances that speed up the way that some body processes work.
- Alkaline phosphatase (ALP).
- Alanine transaminase (ALT).
- Aspartate aminotransferase (AST).
What does a complete metabolic panel do?
With a comprehensive metabolic panel (CMP), you can find out a lot about your health as a whole. With 14 different measurements, it can check a number of body processes and functions, such as:
- The health of your liver and kidneys.
- How much sugar is in your blood.
- Your blood has the right amount of acid and base.
- The balance of fluids and salts in your body.
Why do I need a comprehensive metabolic panel?
A comprehensive metabolic panel (CMP) can be helpful in a number of situations, especially if you have signs of problems with your kidneys, liver, or metabolism. If you have a general symptom, like feeling tired, a CMP measures several important parts of your blood and can help find or rule out some causes of a common symptom.
What’s the difference between a basic metabolic panel and a full metabolic panel?
A basic metabolic panel (BMP) has eight of the 14 tests in a comprehensive metabolic panel (CMP). The liver enzyme and protein tests are not part of a BMP. Depending on your health history and needs, your doctor may have you go through a CMP or a BMP.
