ESLHO EQA program

At ESLHO, we are dedicated to elevating standards in diagnostic testing by providing external quality assessments (EQA) to laboratories worldwide. These assessments are offered through the ESLHO EQA Program, which includes a range of EQA schemes across hematology, immunology, and molecular biology. Our primary goal is to ensure accuracy, reliability, and consistency in diagnostic results. By using solid evaluation processes and offering clear, practical educational support, we help laboratories strengthen their diagnostic skills and deepen their understanding of best practices. This combination of assessment and education boosts laboratory performance and contributes to better patient outcomes.

The EQA schemes are organized by ESLHO in collaboration with subject-matter experts from laboratories within the EuroClonality, EuroFlow, and EuroMRD consortia, who perform relevant diagnostic analyses on a routine basis. The schemes cover diagnostic and monitoring workflows in hemato-oncology and immunology and include immunoglobulin/T-cell receptor (IG/TR) clonality testing, multiparameter flow-cytometry panels (for example, in primary immunodeficiencies, leukemias, and multiple myeloma), and measurable residual disease (MRD) detection using PCR or NGS. The involvement of these expert laboratories is essential due to their high-level expertise and access to high-quality samples and clinical cases, ensuring that the EQA schemes are clinically relevant and of consistently high quality.

We offer the EQA program through the ESLHO EQA Portal. Here you can view the available schemes, find detailed scheme information including costs and timelines for each EQA round, and find which expert laboratories are involved. Interested users can create an account to access additional information (e.g., example instructions and relevant resources). The Portal supports a range of activities, including EQA scheme registration, access to scheme instructions and case files (if applicable), results entry and submission forms, and access to participation certificates and reports. It also allows participants to submit appeals or complaints.
