This test measures the level of bicarbonate in your blood. Bicarbonate is a form of carbon dioxide (CO2). CO2 is a waste product of metabolism. Your blood carries it to your lungs, where it is exhaled. Bicarbonate keeps your blood at the right pH level (not too acidic, and not too basic).
The test is also called a carbon dioxide test or a bicarbonate test.
CO2 testing may be done as part of a group of blood tests (chemistry screen) to help find the cause of many kinds of symptoms, including many kidney diseases, some lung diseases, and metabolic conditions.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
