Blood Discovery: New Hemoglobin Type Found
Scientists at the University of Bonn have discovered a new rare type of haemoglobin. Haemoglobin transports oxygen in the red blood corpuscles. When bound to oxygen it changes colour. The new haemoglobin type appears optically to be transporting little oxygen. Measurements of the blood oxygen level therefore present a similar picture to patients suffering from an inherited cardiac defect. After examining two patients, the scientists now understand that the new type of haemoglobin distorts the level of oxygen measured.
