About Us

The UK National External Quality Assessment Service for Histocompatibility and Immunogenetics (UK NEQAS for H&I) provides a comprehensive range of External Quality Assessment (EQA) Schemes for laboratories operating clinical histocompatibility and immunogenetics (H&I) services.

Schemes are available to all clinical laboratories in the UK and overseas and appropriate biotechnology companies.

H&I laboratory support is universally required for both solid organ and haemopoietic stem cell (HSC) transplant programmes and for HLA typing for disease susceptibility and diagnosis, pharmacogenetics, volunteer HSC donor panels and HLA ‘matched’ blood products. The primary laboratory investigations are the determination of subjects’ HLA type, HLA antibody detection and specification and the direct crossmatching of patients’ sera against donor cells.

UK NEQAS for H&I is hosted by the Welsh Blood Service and operates within the Welsh Transplantation and Immunogenetics Laboratory.

UK NEQAS for H&I is in compliance with the UK NEQAS Code of Practice and is operated by Velindre University NHS Trust, a United Kingdom Accreditation Service (UKAS) accredited proficiency testing provider, No 8351. Further details on our accreditation can be found here.

A full list of UK NEQAS for H&I’s EQA schemes are available in Schemes and Rationale and full details of each scheme along with other useful information is provided in the Participant Manual.
