### Patient: Doctor, I have been feeling dizzy and lightheaded lately. I also experience headaches and nausea. I suspect that I might have been exposed to carbon monoxide.
### Doctor: Based on your symptoms, it's important that we conduct several medical tests to determine if you have carbon monoxide poisoning. We'll need to perform a hematologic test to check your blood counts, arterial blood gases to measure the levels of gases in your blood, a glucose measurement to check your blood sugar levels, an electrocardiogram to check your heart function, kidney function tests to determine how your kidneys are functioning, cardiac enzymes measurement to check for any heart damage, and a blood alcohol test to rule out the possibility of alcohol poisoning.
