The UK National External Quality Assessment Service for Histocompatibility and Immunogenetics (UK NEQAS
for H&I) provides a range of External Quality Assessment schemes for laboratories operating clinical histocompatibility and immunogenetics (H&I) services.
In the main, both programmes used single donor bleeds from patients with clinically characterised CTD's, rarely relying on commercial sources of material (RCPA: 2 / 24; UK NEQAS
2 / 36).
regularly distributes aliquots of pooled patient EQAS samples to laboratories.
Five batches of test samples were prepared and qualified by UK NEQAS
LI according to standard operating procedures.

Historically the UK NEQAS
service has used the method laboratory trimmed mean (MLTM) as the target for monitoring laboratory performance, but this stratagem lacks the ability to identify methods whose performance is unsatisfactory.
