A Comprehensive Metabolic Panel (CMP) is a routine blood test that measures 14 different substances in a sample of blood. It provides important information about the body's fluid balance, levels of electrolytes like sodium and potassium, and how well the kidneys and liver are working
. The CMP includes tests that measure blood levels of glucose, calcium, electrolytes, liver enzymes, and kidney function
. A healthcare professional will take a blood sample from a vein in the arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. The test usually takes less than five minutes
. If you have questions about the CMP or what the test results mean, talk to your doctor
