HLA Typing
The External Quality Assessment Service at the BMT lab, National Cancer Institute provide an external quality assessment (EQA/EPT) service for clinical laboratories. EQA monitors laboratory performance using ‘blind’ samples analyzed as if they were patient samples to ensure testing is comparable, safe and clinically useful to a patient no matter where the testing is performed.
H&I laboratory support is required for:
(i) Solid organ transplantation
(ii) Hematopoietic stem cell transplant programs
(iii) HLA typing as an aid to disease diagnosis, e.g. HLA-B27 and the spondyloarthropathies
(iv) Unrelated hematopoietic stem cell door panels
(v) The provision of HLA/HPA matched blood products
The primary laboratory investigations are:
(vi) Determination of HLA allele type
BMT Lab at NCI, Cairo University Egypt is proud to offer a wide variety of external quality assessment (EQA/EPT) schemes. We use expert knowledge and experience, coupled with a vision for innovation to continually review our schemes in order to maintain their clinical relevance and convenience for our participants.

Individual laboratory performance reports will be available to view on the Participant’s Portal in line with the published report timetable. Participants will also be able to view performance tables detailing the assessment of all participants for a particular distribution. Detailed summaries of methodology used by all Participants in each Scheme will also be available to view.
At the end of each distribution year, an annual performance certificate will be available on the Participant’s Portal for each laboratory, detailing your overall performance for each Scheme you participated in.
In general, performance assessment is based on establishing a consensus result for HLA alleles or all test samples.
Scheme assessment and satisfactory performance criteria are reviewed by the Steering Committee each year and take into account current Standards for Providers’ established by ISO 17043:2023.
The method used to test the samples is generally not considered during scheme assessment. Schemes are generally analyte driven and different methods should give comparable qualitative results.
To establish the consensus result, 75% or more of participant’s results must be in agreement. If there is less than 75% agreement, consensus is not established and that result is not assessed.
A reference result will be used for assessment in the event that a consensus result is not achieved.
Reference typing, will be performed in an ISO15189/CAP accredited laboratory. A laboratory of a Steering Committee member may also be used for a reference result if alternative/additional testing is required.
Participants that have informed the PT Scheme support of a valid reason for not testing EQA sample(s) are marked as ‘Not Tested’ and are not assessed. In these instances, the total number of samples tested on the report is reduced.
Participants that do not submit results without notification are assessed as ‘Unacceptable’. Where a choice of categories for assessment is provided at registration (e.g. HLA loci for HLA Typing) all categories must be reported.
Failure to report a registered assessment category will result in unsatisfactory performance.
