More information about giving blood The following are all the leaflets found at the centres, covering topics that are asked time and time again by donors: Bruising  Although we hope that no donor will have any ill effects from giving blood, occasionally bruising of the arm may develop. The bruise can look very dramatic and some people may find this worrying, especially if it appears away from the donation area or is not visible until the next day. Click here for more Feeling Faint  It is important to be aware that some donors feel faint after giving blood. During blood donation 8-10% of the blood volume is removed. Most people adapt quickly to this loss and their system is not upset by it, but a few individuals adapt less well and consequently feel faint. We hope this will help explain why some donors feel faint after giving blood. Click here for more Haemoglobin and Iron  We check the level of haemoglobin in your blood. This is the red pigment of the blood. It contains iron and carries oxygen from the lungs to the rest of the body. Click here for more Sickle Cell and Blood Donation  The National Blood Service screens donors for sickle cell. This explains why we do this. Click here for more Tests on your blood  You may have noticed that each time you give blood we take blood samples as well as the donation. These samples are used to complete our safety tests back in the laboratory. Click here for more |
