Donation Process

Getting ready to give blood

Registration at the Clinic

When you volunteer to give blood you will be asked to register with the Irish Blood Transfusion Service (IBTS). We ask for your name, address, date of birth and telephone numbers.

You will be asked about specific aspects of your life and medical history and also asked to fill in a health and lifestyle questionnaire. We ask that you read the questionnaire and leaflets provided thoroughly. All the information you give will be treated in the strictest confidence.


Donor Clinics must be conducted in a safe and supportive environment where the dignity of all staff and donors is maintained. Inappropriate behaviour will not be accepted.

Haemoglobin testing

Your Haemoglobin (Hb) will be tested pre-donation using a non-invasive screening test that measures the levels of Hb in the small blood vessels of your finger. If your Hb level is high enough to donate, you will be asked to thoroughly read the information provided to you about donating blood and to complete the questionnaire. For more information on Haemoglobin click here.

Giving Blood

Giving blood then takes approximately 8 to15 minutes. The total volume of blood taken is 470ml, which is less than a pint.


You will then be advised to rest for a short period before going to the canteen where you will be offered a drink and light refreshments.


You’ve saved a life. Thank you and we hope to see you again soon (90 days!!).
