<Tr> <Th> LOINC </Th> <Td> 24322 - 0, 24323 - 8 </Td> </Tr> <P> 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, diabetic and parathyroid status, and electrolyte and fluid balance, but this type of screening has its limitations . Abnormal values from a CMP are often the result of false positives and thus the CMP may need to be repeated (or a more specific test performed), requiring a second blood drawing procedure and possibly additional expense for the patient, even though no disease is present . This test is also known as SMA12 + 2 test . </P> <P> The CMP is an expanded version of the basic metabolic panel (BMP), which does not include liver tests . A CMP (or BMP) can be ordered as part of a routine physical examination, or may be used to monitor a patient with a chronic disease, such as diabetes mellitus or hypertension . </P> <P> Previous names for the panel of tests have been Chem 12, Chemistry panel, Chemistry screen, SMA 12, SMA 20 and SMAC (Sequential Multiple Analysis - Computer). The tests are performed on machines based on the AutoAnalyzer invented in 1957 . </P>
