Clinical Information

Methemoglobinemia - The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)

Sulfhemoglobinemia - A morbid condition due to the presence of sulfmethemoglobin in the blood. It is marked by persistent cyanosis, but the blood count does not reveal any special abnormality in the blood. It is thought to be caused by the action of hydrogen sulfide absorbed from the intestine. (Stedman, 25th ed)
