Blood analysis. Machine used to test donated blood for sickle cell anaemia. Pipettes (silver) are adding reagents to blood samples in a multi-well tray. The subsequent chemical reaction will give either a positive or negative result. Sickle cell anaemia is an inherited disease that mostly affects black people. The red blood cells of those with the disease contain an abnormal form of haemoglobin (blood's oxygen-carrying pigment) that causes the blood cells to become sickle-shaped, rather than round. Sickle cells cannot move through small blood vessels as easily as normal cells and so can cause blockages. This prevents oxygen from reaching the tissues, causes severe pain and organ damage.
