Type of sample to be collected:
Blood (venipuncture—a needle is used to draw blood from a vein)
The CMP measures the blood levels of the following components in the body: blood sugar (glucose), calcium, total protein, liver enzymes (alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase), bilirubin, blood urea nitrogen, creatinine, albumin, carbon dioxide, and the electrolytes sodium, potassium, and chloride. This test provides important information about your body's chemistry and metabolism.
An abnormal CMP result, or a combination of abnormal CMP results, may indicate various health conditions, such as liver or kidney disease, hypertension, or diabetes.
The benefits of testing
You can get the information you need to support a healthy life - for yourself.

Albumin, together with globulin, forms the total protein level on the Comprehensive Metabolic Panel. Globulins are critical for liver function, blood clotting, moving nutrients throughout the body, and fighting infection. Some globulins are produced by the liver; others are made by the immune system in response to an infection or an allergic reaction.
Along with total protein, the CMP indicates the ratio of albumin to globulin (A/G ratio) to detect whether your protein level is abnormal. If your total protein level and A/G ratio are abnormal, this may indicate that your body is not digesting or absorbing proteins properly or that your kidney or liver are not functioning correctly. If your A/G ratio is excessively high or low, further blood and urine testing may be suggested.
Creatinine, BUN, and estimated glomerular filtration rate (eGFR) provide information about the overall health of the kidneys. The kidneys filter creatinine and BUN from the blood and remove them from the body. An eGFR measures how much blood the renal glomeruli remove every minute based on your body size, indicating how efficiently the kidneys are functioning.
In addition, a CMP includes a BUN/Creatinine ratio—which, if elevated, may suggest a condition that causes decreased blood flow to the kidneys, such as dehydration or congestive heart failure.
