A carbon monoxide (CO) blood test measures how much CO is attached to hemoglobin, the protein that carries oxygen in your blood. It is ordered when someone has symptoms like headache, dizziness, or confusion that might be from smoke, car exhaust, or faulty heaters, or to check exposure in certain jobs.
What it measures
- Carboxyhemoglobin (COHb) — The percentage of hemoglobin carrying carbon monoxide instead of oxygen.
- Hemoglobin (Hb) — The total amount of oxygen-carrying protein in your blood.
- Oxygen saturation (SaO2) — How much oxygen is attached to hemoglobin, often measured alongside COHb.
- Methemoglobin (MetHb) — A form of hemoglobin that cannot carry oxygen; sometimes checked to rule out other causes.
Who it is for
A doctor may order this test if you have unexplained symptoms of CO exposure, such as headache, nausea, or confusion, especially if others in the same building have similar symptoms. It is also used for people who work with combustion engines, furnaces, or in firefighting.
Preparation
No fasting or special preparation is needed. Tell your doctor if you smoke, because smoking can raise your baseline CO level.
Results and what they mean
Results are reported as a percentage of carboxyhemoglobin. Normal levels are usually low, but interpretation depends on whether you smoke and your symptoms. Only a clinician can interpret your results in context; this information is not medical advice.
