Haemoglobin

Patients with sickle cell anemia have abnormal haemoglobin that can cause their red blood cells to become misshapen.

A decrease in haemoglobin concentration can cause fatigue and weakness.

Oxygen binds to haemoglobin in the lungs and is transported to the body's tissues.

The hospital uses a machine to measure the amount of haemoglobin in a patient's blood sample.
