comprehensive metabolic panel , or chemical screen , ( CMP ; CPT code 80053) is a panel of 14 blood tests that serves as the initial area of ​​medical screening tools. CMP provides a rough examination of renal function, liver function, diabetes and parathyroid status, and electrolyte and fluid balance, but this type of screening has its limitations. The abnormal value of CMP is often the result of false positives and thus CMP may need to be repeated (or more specific tests performed), requiring a second blood-taking procedure and possibly an additional cost for the patient, although no illness is present.. This test is also known as the test SMA12 2.
CMP is an expanded version of the basic metabolic panel (BMP), which does not include liver tests. CMP (or BMP) may be ordered as part of a routine physical examination, or may be used to monitor patients with chronic diseases, such as diabetes mellitus or hypertension.
The previous name for the test panel has Chem 12 , Chemical panel , Chemistry screen , SMA 12 , 20 and SMAC (Double Ordered - Computer Analysis). Tests were performed on machines based on AutoAnalyzer found in 1957.

Test
Usually, the patient fasts for ten or twelve hours before blood is taken for the test - it is very important to get a useful blood glucose measurement. CMPs are also often performed in patients who are not fasting, but glucose levels in these cases are not very useful. The following test is then performed:
General test
These tests help screen for various problems. Special glucose tests help screen for diabetes mellitus and pre-diabetes. Calcium tests can show or monitor bone disease or diseases of the parathyroid or kidney glands. Calcium, lithium salts, thiazide diuretics, thyroxine, and vitamin D can increase levels and may interfere with this test.
- Serum glucose
- Calcium
Assessment of kidney function
- Blood urea nitrogen (BUN)
- Creatinine
Electrolytes
The level of electrolyte and balance are strictly regulated by the body. Both individual values ​​and ratios among values ​​are significant; abnormalities between the two may indicate problems such as electrolyte disturbance, acid-base imbalance, or renal dysfunction.
- Sodium
- Potassium
- Chloride
- Carbon dioxide (CO 2 )
The protein test
Test protein levels in the blood relief screen for both kidney and liver disorders.
- Total protein serum (TP)
- Human serum albumum
Assessment of liver function
- Bilirubin
- Alkaline phosphatase (ALP)
- Aspartate amino transferase (AST or SGOT)
- Alanine amino transferase (ALT or SGPT)
