Comprehensive Metabolic Panel (CMP) Test
A comprehensive metabolic panel (CMP) is a routine blood test that measures 14 different substances to check your metabolism and the balance of chemicals in your body. It gives information about your liver and kidney health, blood sugar, protein levels, and fluid and electrolyte balance.
What this test measures
A CMP measures glucose, calcium, sodium, potassium, bicarbonate, chloride, albumin, total protein, ALP, ALT, AST, bilirubin, BUN, and creatinine. These substances provide information about your metabolism, liver and kidney function, blood sugar, protein levels, and fluid and electrolyte balance.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Higher-than-normal results
According to the source, if you have one or more results that aren't normal, it may be a sign of a health condition. For example, high blood glucose may be a sign of diabetes.
