How often can I give blood?.
Male donors can donate 4 times in 12 months with a minimum interval of 12 weeks between donations. We advise female donors to donate at an average of 16 weeks or more to reduce the risk of iron deficiency.
How much blood will be taken?
Only about 470ml, which is just under a pint. Your body will replace the lost fluid in a very short period of time.
Will I be asked a lot of questions before I give blood?
We will ask you a number of questions, but we promise to get through it all as quickly as possible. Our primary concerns are that giving blood will not harm you in any way and that your blood will be safe for patients
How will giving blood affect my health?
If you are fit and healthy, you should not experience any problems whatsoever.
Why can women donate less frequently than men?
Female donors do not have the same levels of stored iron as male donors for lots of reasons. This means that they cannot donate as often as their male counterparts as to do so could potentially put them at risk of anaemia and NHSBT will never risk the health of donors.
Is it safe for men to donate more frequently?
Male donors who give a whole blood donation can safely donate four times a year, as long as they wait twelve weeks between donations. This allows them to improve the lives of thousands more people every year! Allowing male whole blood donors to donate more often is a great step forward in meeting the 8,000 units needed every day to meet hospital demands.
What can I do before and after giving blood?
Be sure to eat at your regular mealtimes and drink plenty of fluids before and after donating, but avoid alcohol.
Can I smoke after giving blood?
We advise that you refrain from smoking for about two hours after donating, as it might make you feel dizzy or faint.
What if I feel faint when I get home?
You need to take it easy for a few hours after giving blood, but if you do feel faint or dizzy, lie down immediately with your legs raised. Ideally, let someone else know if you are feeling unwell. If faintness persists after your donation, don't hesitate to call us on 0300 123 23 23 to let us know and we will be able to advise you further..
Where does my blood go?
Your blood will be taken to one of our blood centres up and down the country. To protect patients, your blood is tested for HIV, hepatitis B and C, certain other infectious diseases and syphilis. Once the blood has been sorted into its different types, and all the tests are clear, it is then distributed to hospitals to meet their predicted demand. There your blood is matched to a particular patient who requires a transfusion. View the current blood stock levels.
