International External Quality Assessment Scheme (IEQAS)


138 HTCs from 87 countries are currently registered with the IEQAS scheme (13 new added in 2018).

The World Federation of Hemophilia’s (WFH) International External Quality Assessment Scheme (IEQAS) was launched in 2004 to monitor and improve laboratory performance in hemophilia treatment centres (HTC) worldwide. Laboratories can participate in this scheme to assess their quality assurance systems and the reliability of their test results.

IEQAS improves and standardizes laboratory diagnosis by auditing the effectiveness of the internal quality assurance systems in place and giving a measure of the laboratory’s competence.

The scheme is operated by the United Kingdom’s National External Quality Assessment Scheme (UK NEQAS) for Blood Coagulation, based in Sheffield. For more information consult the following links from their website:

Participating in IEQAS

Laboratories interested in joining the IEQAS program should contact Thalia De Anda at

Selection Criteria

Laboratories are chosen based on their involvement in the diagnosis of hemophilia and other bleeding disorders. From each country, there is usually one main reference laboratory enrolled in IEQAS. In larger countries, several laboratories may enroll in the scheme.

Application Process

Each December, the WFH reviews new applications from centres interested in participating, and also reviews centres currently enrolled in the program. Those selected to participate for the upcoming year will be contacted by the WFH.

These selected centres will be asked to submit a form to the WFH confirming their enrollment in the program. All new centres will also be asked to complete a laboratory questionnaire.

Enrollment fee

£275 per year (approximately US$335), per centre, for the cost of 3 surveys.
