The comprehensive metabolic panel, or chemical screen, (CMP; CPT code 80053) is a panel of 14 blood tests which serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, and electrolyte and fluid balance, but it is far from perfect. Abnormal values from a CBC may be a result of false positives and thus the CBC may need to be repeated for a patient (or replaced with a more specific test).
The comprehensive metabolic panel (CMP) gives your healthcare provider important information about the status of your kidneys and liver and electrolyte and acid/base balance and levels of blood glucose and blood proteins
A basic metabolic panel (BMP), commonly ordered as part of routine medical exam, is a set of blood tests that gives information about sugar (glucose) and calcium levels, kidney function, and electrolyte and fluid balance.
