Kidney and liver function, electrolytes, acid/base balance, blood glucose and blood proteins are all measured in a CMP, explains LabTestsOnline. Test results that fall outside the normal range may indicate a condition that needs treatment. Kidney disease, liver disease and diabetes are examples of conditions that can be diagnosed or monitored by a CMP.

There is little preparation required for a CMP, notes MedlinePlus, although an accurate blood glucose measurement requires fasting for at least eight hours. Otherwise, a phlebotomist performs a routine blood draw, or venipuncture, for the test.

The CMP is related to the basic metabolic panel, or BMP, states LabTestsOnline. The basic panel is an eight-test subset of the 14-test comprehensive panel. It doesn't contain the liver and protein tests like the comprehensive panel does. A doctor usually chooses a comprehensive panel when he wants a broader overview of the body's functioning or is monitoring a specific condition.
