Do you know what CMP blood test is? It stands for comprehensive metabolic profile or comprehensive metabolic profile and it is frequently ordered by doctors to check the status of the blood proteins, blood sugar, acid/base balance, electrolyte, liver, and kidneys. If the readings of the results reveal abnormalities, the doctor can conduct further tests to give an accurate diagnosis.
The CMP testing is actually a group of tests and each test has an assigned current procedural terminology code. Laboratories are free to adjust the tests being conducted, as they see fit. It is vital that you know the CPT codes since you will use them when you file for claims with the insurance provider. In the US, the tests have already been standardized.
The CMP can test for glucose, calcium, proteins (albumin and the total protein), electrolytes (sodium, potassium, CO2, and chloride), kidney tests (blood urea nitrogen and creatinine), and liver tests (alkaline phoshatase, alanine amino transferase or SGPT, aspartate amino transferase or SGOT, and bilirubin). It is important that an increase or decrease in glucose or calcium is determined. This is also true with the total protein wherein albumin and other proteins are measured.
When there is an imbalance in the electrolytes, it can indicate chronic and acute illnesses. In most cases, the examination for electrolytes is carried together with other tests and is rarely ordered individually. If there is an increase of BUN and creatinine in the blood, it can mean that the kidneys are not functioning well. When tests reveal that there is an elevated concentration of the AST, ALT, and ALP in the blood, it can indicate a liver dysfunction or disease.
Once your doctor requests for the CMP, you have to ask if there is a need to fast before the blood is drawn from your arm. Follow the instructions of the medical professional so that the test can provide reliable readings. This will usually depend on the reason why the CMP was ordered. Most professionals use this test to identify if a patient has kidney disease, liver disease, and diabetes. In some cases, it can also be used to monitor side effects of kidney or liver related conditions and hypertension.
The comprehensive metabolic profile test is usually ordered for yearly physicals or part of the routine checks. In most cases, the patient should avoid food or water intake for 10-12 hours prior to the test. Ask the medical practitioner about the costs involved, and the implications that the readings can have on your health.
