Carbon Dioxide (Bicarbonate)

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include the following:

  • You drink liquids that are very acidic, such as orange juice or some types of carbonated beverages, shortly before having the test.
  • You are taking some medicines, such as diuretics, some antibiotics, glaucoma medicine, and corticosteroids.
  • The health professional leaves on the elastic band that stops blood flow for an extended amount of time before the blood sample is collected.

What To Think About

  • The carbon dioxide (bicarbonate) test also can be done on a blood sample taken from an artery for an arterial blood gas (ABG) test. To learn more, see the topic Arterial Blood Gases.
