ESLHO

What ESLHO does

ESLHO (European Scientific foundation for Laboratory Hemato Oncology) is a Dutch non-profit foundation incorporated in 2009 that operates as an umbrella organization for three scientific consortia — EuroClonality, EuroFlow, and EuroMRD — focused on innovation, standardization, quality control, and education in laboratory diagnostics for lymphoid malignancies. The foundation supports over 115 European diagnostic laboratories that participate in its networks and consumes its standardized protocols, including the BIOMED-2 multiplex PCR assays (gold standard since 2003 with >3,800 citations), EuroFlow antibody panels (LST, PIDOT, MM MRD, BCP-ALL MRD), and EuroMRD interpretation guidelines for RQ-PCR and NGS-based measurable residual disease (MRD) detection.

Its core product surface is the ESLHO EQA Portal (eqa.eslho.org), launched in January 2025 and unified across all three consortia as of January 2026, which manages registration, result submission, and certificate access for 14 distinct External Quality Assessment schemes spanning IG/TR clonality testing, flow cytometry panels, and molecular MRD detection (including pilot ctDNA and dPCR/NGS-based schemes). The foundation also runs an annual scientific symposium (15th edition in Leiden, November 2026), Summer/Winter Schools (EuroFlow), and EHA Specialized Working Group sessions, and provides IVDR compliance guidance through a BioMed Alliance In Vitro Diagnostics Task Force seat.

ESLHO's revenue model is fee-based and subscription-recurring: EQA scheme participation fees range from free (for consortium members) to €460-€490 per scheme for non-members, plus a separate annual EuroMRD membership fee and unit-priced additional certificates (€110 per extra LST certificate). The organization operates with 1-10 employees out of Zutphen, Netherlands, and is governed as a foundation under Dutch law (Chamber of Commerce No. 34457776, Rotterdam) with EHA Specialized Working Group status. ISO 17043 Proficiency Testing Provider accreditation has been applied for as of 2024-2025 to formalize the EQA operation.

Core offering

ESLHO provides External Quality Assessment (EQA) schemes, standardized diagnostic protocols, and educational programs for clinical laboratories focused on lymphoid malignancies. The foundation coordinates three scientific consortia—EuroClonality (molecular clonality testing), EuroFlow (flow cytometry), and EuroMRD (measurable residual disease detection)—and operates the ESLHO EQA Portal for sample registration, payment processing, and results reporting across participating laboratories worldwide.

Product overview

ESLHO (European Scientific foundation for Laboratory Hemato Oncology) operates primarily through its ESLHO EQA Portal, a unified web-based platform for managing External Quality Assessment (EQA) schemes across three scientific consortia: EuroClonality, EuroFlow, and EuroMRD. The organization offers a portfolio of 14 distinct EQA schemes covering laboratory diagnostics for lymphoid malignancies and primary immunodeficiencies. These include EuroClonality IG/TR clonality testing schemes, EuroFlow flow cytometry-based schemes (LST for lymphoid screening, PIDOT for primary immunodeficiency, MM MRD for multiple myeloma, and BCP-ALL MRD for B-cell precursor ALL), and EuroMRD molecular-based schemes (ALL, NHL, KMT2A, Ph+ALL, dPCR-based, and NGS-based MRD detection schemes). The platform serves diagnostic laboratories worldwide, providing standardized quality assessment for hematology and immunology laboratory diagnostics.
