Any carbon monoxide levels above normal is considered dangerous.
1 Non-smokers living away from urban areas have normal carbon monoxide levels in the blood stream of 0.4% to 1.0%. 2  Carbon monoxide levels of 1% to 5% may be considered normal if a person lives in a busy urban or industrial setting. 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, may allow carbon monoxide to accumulate to dangerous levels. Test Overview. A carbon monoxide blood test is used to detect poisoning from breathing carbon monoxide (CO), a colorless, odorless, poisonous gas. The test measures the amount of hemoglobin that has bonded with carbon monoxide. This amount is also called the carboxyhemoglobin level. A person with relatively low carbon monoxide levels and mild symptoms can actually be seriously poisoned. Many factors play a role in the severity of symptoms while in the body, short term symptoms and effects, long term effects, and the damage caused by carbon monoxide poisoning. Low carbon monoxide levels in the blood stream (COHb) and cellular tissues are normal and necessary for proper cellular functioning. However there is not uniform agreement as to what normal levels in the blood stream are within different environments. Any carbon monoxide levels above normal is considered dangerous. Carbon monoxide levels in the blood stream cannot easily be measured outside a medical setting. Carbon monoxide levels are often shown as concentration levels of parts per million (PPM) in the air and length of exposure. Carbon Monoxide (CO). Guide. A carbon monoxide blood test is used to detect carbon monoxide poisoning. Poisoning can happen if you breathe air that contains too much carbon monoxide (CO). This gas has no color, odor, or taste, so you can't tell when you are breathing it.
