The Comprehensive Metabolic Panel (CMP) is a frequently ordered panel of tests that gives your doctor important information about the current status of your kidneys, liver, and electrolyte and acid/base balance as well as of your blood sugar and blood proteins. Abnormal results, and especially combination of abnormal results, can indicate a problem that needs to be treated.
In our reports you will be shown not only your results, but also the normal ranges of the given tests. it is highly recommended that you consult with your physician to determine the meaning of the data provided. Abnormal results, and especially combinations of abnormal results, can indicate a problem that needs to be addressed.
We recommend this test or one of the other CMP or BMP tests prior to seeing you physician for a yearly physical. It will save you time and money, in all probability.
The CMP is comprised of 14 specific tests that have been approved, named, and are considered standard throughout the United States. Your physician may choose to add on additional tests, all of which are generally available on FairCareMD.
The CMP includes:
* Glucose * Calcium * Albumin Albumin is the major protein in the serum portion of your blood. * Total Protein
* Sodium * Potassium * CO2 (carbon dioxide, bicarbonate) * Chloride
The balance of these substances in your blood is indicative of various changes in wellness and lifestyle as well as possibly disease states.
* BUN (blood urea nitrogen) * Creatinine
BUN and creatinine are waste products filtered out of the blood by healthy kidneys. Increased concentrations in the blood may indicate a temporary or chronic decrease in kidney function. When not ordered as part of the CMP, they are still usually ordered together.
* ALP (alkaline phosphatase) * ALT (alanine amino transferase, also called SGPT) * AST (aspartate amino transferase, also called SGOT) * Bilirubin
ALP, ALT, and AST are enzymes found in the liver and other tissues. Bilirubin is a waste product produced by the liver as it breaks down and recycles aged red blood cells. All can be found in elevated concentrations in the blood with liver disease or dysfunction.
How is the sample collected for testing? The CMP uses a tube of blood collected by inserting a needle into a vein in your arm. Ask your doctor whether you should be fasting for 10 to 12 hours prior to the blood draw. Depending on the reason for ordering the CMP, it may be drawn after fasting or on a random basis.
How is it used? The CMP is used as a broad screening tool to evaluate organ function and check for conditions such as diabetes, liver disease, and kidney disease. The CMP may also be ordered to monitor known conditions, such as hypertension, and to monitor patients taking specific medications for any kidney- or liver-related side effects. If your doctor is interested in following two or more individual CMP components, he may order the entire CMP because it offers more information.
When is it ordered? The CMP is routinely ordered as part of a blood work-up for a medical exam or yearly physical. Although it may be performed on a random basis, the CMP sample is usually collected after a 10 to 12 hour fast (no food or liquids other than water). While the individual tests are sensitive, they do not usually tell your doctor specifically what is wrong. Abnormal test results or groups of test results are usually followed up with other specific tests to confirm or rule out a suspected diagnosis.
