A comprehensive metabolic profile, also known as a CMP, is a series of tests that are used to assess the health of your kidneys, liver, electrolyte, and acid/base balance.
The CMP includes 14 different tests, each of which provides important information about how these organs are functioning.
The Tests Included in a CMP Are:
- Blood urea nitrogen (BUN)
- Creatinine
- Glucose
- Calcium
- Carbon dioxide (CO2) or bicarbonate (HCO3)
- Chloride
- Potassium
- Sodium
- Albumin
- Alkaline phosphatase (ALP)
- Alanine aminotransferase (ALT) or glutamic pyruvic transaminase (SGPT)
- Aspartate aminotransferase (AST) or glutamic oxaloacetic transaminase (SGOT)
- Total bilirubin
- Protein electrophoresis
These tests can help doctors identify problems with the way your kidneys and liver are functioning, as well as problems with your electrolyte and acid/base balance.
If you have symptoms that may be indicative of kidney or liver disease, your doctor may order a CMP to help diagnose the problem.
The CMP is also often used to monitor patients who have been diagnosed with kidney or liver disease, to see how well they are responding to treatment.
Do You Need to Fast Before a CMP Test?
You will need to refrain from eating or drinking for 10-12 hours before your blood test. Eating before the blood test can cause elevated blood sugar levels. A fasting blood glucose level is needed. Your doctor will provide you with appropriate instructions.
