Carbon Monoxide, Blood Test

This blood test is used to determine the extent of carbon monoxide poisoning and toxicity. Test Includes checking Carboxyhemoglobin.
Carbon monoxide poisoning occurs when carbon monoxide builds up in the bloodstream. When too much carbon monoxide is in the air, your body replaces the oxygen in your red blood cells with carbon monoxide instead. They bind together stronger than oxygen does, which can lead to serious tissue damage and even death.
Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gas, wood, propane, charcoal or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space like a garage, may allow carbon monoxide to accumulate to dangerous levels.
