Giving Blood

The Welsh Blood Service organises the collection, testing, processing and distribution of blood. We rely entirely on voluntary donors to maintain supplies to Welsh hospitals.

We need to collect over 350 donations of blood everyday and demand has risen steadily over the last 10 years as medical techniques become evermore sophisticated.

Anyone aged between 17 and 66, who weighs over 7st 12lbs (50kg), who is healthy and not subject to certain medical exclusions can volunteer to become a blood donor.

If you are a female donor age 17 – 19 years please visit our FAQ’s for further information.

Why do we collect blood donations?

Throughout medical history it has been proved that blood and its by-products have played a vital role in saving lives. Most donors do not realise what we use their donations for. The blood we collect is not just used for emergency operations or accident victims. So many patients could not survive without blood transfusions, such as anyone having a kidney, liver or an organ transplant; leukaemia and cancer patients; patients having cardiac operations and many premature babies just cannot survive without blood transfusions.

Why should you become a donor?

Today we are required to supply 350 donations a day to the hospitals in Wales. A single donation can be broken down into its different components, so it can be used in various ways. These components all have differing life spans:

Platelets/White cells – 7 days

Red Cells – 35 days

Plasma can be frozen for up to 3 years.

How often can I donate?

Male donors must wait a minimum of 12 full weeks between each blood donation and can give up to 4 donations in a calendar year.

Female donors must wait a minimum of 16 full weeks between each blood donation and can give up to 3 donations in a calendar year.

We can’t supply our hospitals in Wales without you!
