Biology 101 taught us that the body takes in oxygen when we inhale and lets out carbon dioxide when we exhale. This natural function helps us maintain a healthy level of carbon dioxide (in the form of the electrolyte called bicarbonate). But certain medical conditions—such as electrolyte imbalance, metabolic disorders, or kidney or lung issues—can interfere with the process. Checking the CO2 levels in the blood can help diagnose a health problem; this test is often part of a regular wellness visit, whether performed on its own or as part of a basic metabolic panel.
This blood test shows how much CO2 is in your body.
Blood work for CO2 is often ordered as part of an annual wellness checkup. There are certain symptoms that may also call for a carbon dioxide blood test, including fatigue, persistent diarrhea or vomiting, disorientation, weakness, and respiratory problems.
There’s nothing special you need to do before taking a CO2 test.
Generally, the normal range for carbon dioxide test results is 20 to 29 mmol/L, which stands for millimoles per liter. Results outside the range may require further investigation, such as lung or kidney testing. If you have questions about your CO2 lab test, contact Personalabs to set up a telehealth visit with an experienced, board-certified physician. If you don’t have any symptoms, you may want to monitor your CO2 levels every year to ensure they haven’t changed.
