The Welsh Blood Service plays a fundamental role in the delivery of healthcare in Wales. The Welsh Blood Service covers the whole of Wales. We collect voluntary, non-remunerated blood donations from the general public. These donations are processed and tested before distribution to hospitals where they support patient care. We also hold blood-derived products (both NHS and Commercial) for purchase by our customer hospitals.

We provide an antenatal screening service to several hospitals and offer all customer hospitals specialist laboratory services to assist in the investigation of complex serological problems.

The Welsh Transplantation & Immunogenetics Laboratory, within the WBS, provides direct support to local providers of Renal and Stem Cell Transplant Services. It also operates a national panel of unrelated potential blood stem cell donors – the Welsh Bone Marrow Donor Registry.

The WBS is authorised and licenced by the Medicines and Healthcare products Regulatory Agency, who audit the organisation at defined periods.
