Carboxyhaemoglobin

Carboxyhaemoglobin


The Carboxyhaemoglobin blood test checks how much carbon monoxide is bound to your haemoglobin (the protein in red blood cells that carries oxygen). When carbon monoxide enters the body, it reduces the blood’s ability to carry oxygen effectively. Elevated levels may indicate recent exposure to carbon monoxide from sources such as faulty heating systems, smoke inhalation, or heavy smoking. Early detection is important, as high levels can lead to serious health complications.
