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.
The blood test for aspartate aminotransferase (AST) is usually used to detect liver damage. It is often ordered as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disorders.
