The main difference between a CMP (Comprehensive Metabolic Panel) and a BMP (Basic Metabolic Panel) is that a CMP provides more extensive blood test information than a BMP, including assessments of liver function. A BMP includes 8 tests that measure glucose, calcium, electrolytes (sodium, potassium, carbon dioxide, chloride), and kidney function (BUN and creatinine) 1. A CMP includes all BMP components plus 6 additional tests that assess liver function (albumin, total protein, ALP, ALT, AST, and bilirubin). Some studies have discussed the importance of signaling cross-talk between different pathways, including TGF-beta/BMP, in various cellular processes 1. However, these studies do not provide direct information about the difference between CMP and BMP. Doctors typically order a BMP for routine check-ups or to monitor conditions like high blood pressure or kidney disease, while a CMP is ordered when more comprehensive information about both liver and kidney function is needed. Both tests require a blood sample and are commonly performed during regular physical examinations or when evaluating specific health concerns. The CMP provides a more complete picture of metabolic health but costs slightly more than the BMP due to the additional tests included. It is essential to note that the provided evidence does not directly address the question, but based on general medical knowledge, the CMP is a more comprehensive test that includes all the components of the BMP, as well as additional tests to assess liver function. In clinical practice, the choice between a CMP and a BMP depends on the patient's specific needs and the physician's judgment, considering factors such as the patient's medical history, symptoms, and the potential benefits and risks of each test. Some studies have discussed the use of combination therapies in treating various diseases, including cancer 2, 3, 4, 5, but these studies are not relevant to the difference between CMP and BMP. In summary, the CMP is a more comprehensive test that provides a complete picture of metabolic health, including liver and kidney function, while the BMP is a more basic test that measures glucose, calcium, electrolytes, and kidney function.
