From the moment you arrive at your donation session, we will guide you through the process, explain what we are doing and answer any questions you may have about becoming a blood donor.
Welcome and preparation
Before donating blood, please eat regular meals, drink plenty of fluid (non-alcoholic) and avoid vigorous exercise or exertion.

Remember to bring your completed Donor Safety Check form with you, if you received one from us in the post. If you ever need to cancel a donation appointment we ask that you give us 3 days’ notice so that we can offer your appointment to another donor. You can easily cancel or reschedule your existing appointments by logging in to your online account or using the NHS Give Blood app.
When you attend your donation session please read our donor consent information booklet – this explains the importance of blood safety. It’s important to read this every time you attend, because advice does change.
We must give you sufficient information so that you can make an informed choice, on the benefits and risks of donating blood and samples for testing.
We will provide 500ml of fluid just before you donate. By drinking this over about 5 minutes, it will help with your wellbeing during and after donation.
Health screening
You will be called for private health screening, where a donor carer will confirm your identity. It’s critical that we guarantee an accurate link between you, your Donor Safety Check and your donation.
We must ensure that it’s safe for you to donate and your donation is safe for a patient to receive. We’ll ask some confidential questions based on your completed Donor Safety Check.
There is a period of time from contact with any infection to detecting markers in the laboratory. We trust your honesty when answering these personal questions. This will ensure your blood is safe to transfuse to patients.

You may be referred to a registered nurse for certain medical queries: their uniforms have white or red piping on the collar and cuffs. An explanation will always be provided if you are not able to donate. You will be advised when you can donate, and we’ll encourage you to make an appointment before you leave (the team are only able to book future appointments for the venue they are currently at).
For your wellbeing, we must ensure you have enough haemoglobin (iron) in your blood before donating. Your test involves us taking a small blood drop from your finger to firstly test your iron levels by dropping the blood into a vial of copper sulphate solution. If the blood sinks to the bottom in a set time, you can give blood.
If the blood floats or does not sink in one continuous motion, we will offer you a further test using a HemoCue machine. This test requires a drop of blood from your fingertip which is tested in the machine to give your haemoglobin level. Your haemoglobin result helps us decide if you are able to give blood or if you need to wait some time before returning to donate blood.
Following health screening, you will be asked to sit in a different waiting area. From here you’ll be called and invited to a donation chair. You can find out more about health and travel eligibility for blood donors here.
Your donation
When you are comfortable on the chair, you will be asked your name, address and date of birth again.
Blood bags and sample tubes are labelled with unique donor identification numbers. All collection equipment is single use and sterile; only one blood bag is filled with your donation.
A blood pressure cuff will be placed on your arm to maintain a small amount of pressure during your donation. The cuff is not used to measure blood pressure.
Your arm will be thoroughly examined to find a suitable vein. If we’re unable to draw blood first time, we will not make a second attempt on a less suitable vein – this is to keep all our donors safe.
We will then use an antiseptic sponge to clean your arm. This kills normal bacteria (germs) on the skin. You will see staff cleaning their hands frequently, using hand wipes or gels.
Donors are advised to do applied muscle tension exercises during donation. This is to maintain blood pressure and promote wellbeing during and after donation.

Following needle insertion you should be comfortable during your donation. If you experience any discomfort or pain please alert a member of staff.
An agitator scale constantly weighs and measures your donation. It will stop automatically when your donation is complete. Donor carers will be available to you throughout your donation.
You may hear beeping noises from the agitator, these inform us of the progress of your donation. A full donation is 470ml and will usually take between 5 and 10 minutes.
If you require assistance or have any concerns, please make us aware by raising your non-donation arm. After donation, the needle will be removed and a sterile dressing applied to your arm.
We advise that you leave the pressure roll on for 30 minutes and the plaster dressing on for 6 hours. Please avoid using this arm to push on or to carry anything heavy.
We will give you a card at the end of your donation with important care advice. Donors are also asked to apply additional pressure to the venepuncture site while waiting for their drink at the refreshment area.
After donation refreshment
A selection of drinks and snacks are available at the refreshment table. We encourage donors to relax here for at least 15 minutes and to have at least 2 drinks following donation.
If you feel unwell, please remain seated and alert a member of staff immediately. Where possible, we encourage you to book an appointment for your next donation.
At home
If you become unwell (other than a cold or cold-sore) within 2 weeks following your donation, or if you believe there is a reason your blood should not be given to a patient, please call our donor helpline on 0300 123 23 23.
Please do not have a hot bath on the day of your donation.
