A Chem 14 blood test, also called a comprehensive metabolic panel, is a group of 14 tests used to check organ function and monitor certain health conditions. A Chem 14 measures blood levels of sodium, potassium, chloride, bicarbonate and glucose. It also evaluates kidney and liver function.
Doctors usually order a Chem 14 blood test as part of a medical exam or annual physical. Some patients may be required not to eat or drink for 10 to 12 hours prior to the test. The results of a Chem 14 generally cannot diagnose a specific health condition, but they are useful in directing further testing.
