Hereditary Hearing Loss
Testing for Hereditary Hearing Loss. This EQA has options for panel testing and targeted DFNB1 (GJB2 and GJB6) testing
Overview
The scheme is designed to assess the entire diagnostic pipeline of a laboratory, including sample receipt and processing, analytical processing (genotyping), and reporting (biological and clinical interpretation of the test result) in the context of a clinical referral, as well as reporting clarity, content and clerical accuracy.

Sample Details
Three mock clinical cases with matching samples will be provided, 2 with matching samples and 1 virtual case.
Approximately 2.0µg DNA per sample is provided.
EQA Results
Participants will receive an individual report including educational advice and a scheme report which includes additional information from the cohort of participants including geographical spread, methodologies employed, common errors, learning points and scheme statistics allowing participants to benchmark their results.
Each laboratory will also receive a single certificate listing all EQAs participated in with performance result for each year.
Participation Information
Participants are expected to test samples according to their routine strategy, to return a clinical report and to complete the data collection form.
Panel testing can be performed using any appropriate panel for genes associated with hereditary hearing loss. To account for differing panel compositions, variants outside the stated scope of an individual laboratory’s panel will be excluded from their assessment. Only variants that have been validated in the test samples will be assessed.
No restrictions on number of participants. Open to laboratories from ALL countries (note: some restrictions may apply due to sanctions, delivery network exceptions, restrictions on importation etc).
