The<unk> , or chemical screen <unk> ; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The<unk>  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<unk>  are often the result of false positives and thus the<unk>  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. The<unk>  is an expanded version of the basic metabolic panel (BMP), which does not include liver tests. A<unk>  (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. 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.
