The 5 steps of giving blood
1) Before giving blood participants you must register with the NHS to prove that you blood is suitable to be used in medical procedures. This is usually done online where a small series of screening questions are answered. Once registered you are then able to book an appointment at a blood centre.
2) Upon arriving at the blood centre you are given a welcome leaflet and are asked to drink 500ml of fluid before you give blood.
3) You will then go through a health screening and a blood sample will be taken to check that your iron levels are sufficient to undergo the procedure. If they are not you may be asked to come back another day.
4) You will then be taken to a chair where a nurse place is a cuff upon your arm to maintain some pressure. Once a suitable vein has been found and neither will be inserted into your arm and then blood will be collected into a bag containing your unique door number. If you are worried about the pain of the procedure the sensation can be compared to a light scratch when the needle first breaks the skin.
5) After the procedure has taken place you will be able to sit and relax taking on board some fluids giving your body time to deal with the procedure. The blood bag will then be collected and is usually used to save lives within seven days.
