In order to move the field of LB forward and in line with our holistic approach, the ELBS consists of distinct working groups that combine specific areas of expertize. The working groups (WGs) are Dissemination & Education, Clinical, Technology, and Regulatory Issues. Each WG is chaired by a steering committee of 2 – 4 members that drive the activity of the network in their specific area of expertize. More information on the WGs can be found under the respective links below.


  • The goal of the Education & Dissemination WG is to build a strong and interconnected network with all essential players on board.

    This is achieved by:

    • Establishing connections to other scientific societies and initiatives in the liquid biopsy space
    • Generating awareness of liquid biopsy applications for researchers, clinicians and others
    • Increasing knowledge in relevant areas of the LB field (through workshops, white papers, etc.)
    • Online representation


  • The goal of the Clinical WG is to translate clinical insights on liquid biopsy applications into clinical utility.

    This is achieved by:

    • Identification of urgent clinical needs (markers and assays)
    • Identification of relevant projects from a clinical perspective
    • Providing guidance and a clinical perspective for the other WGs
    • Defining good practice criteria for inclusion of LB in clinical trials
    • Revising and designing “ELBS approved” clinical trials in the realm of LB


  • The technology working groups are subdivided according to their focus. Currently 3 WGs exist spanning the CTC, ctDNA, and EV fields. The overarching goal of these groups is to identify optimally suited assays for specific scientific and clinical questions and to work towards optimization, harmonization and standardization of these methods.

    Activities include, but are not limited to:

    • Benchmarking novel technologies
    • Establishing and improving SOPs
    • Organizing ring trials to assess and compare technology proficiency
    • Educating on limitations, challenges and strengths of existing analytical approaches
    • Supporting interested labs in standardization and certification processes (e.g. ISO 15189)


    CTC WORK GROUP: Evi Lianidou, Nikolas Stöcklein and Yong-Jie Lu

    ctDNA WORK GROUP: Ellen Heitzer, Ed Schuuring and Patrizio Giacomini

    EV WORK GROUP: An Hendrix, Rienk Nieuwland and Franz Ricklefs

  • The regulatory WG pursues the overarching goal of driving implementation and the introduction of liquid biopsy assays into routine clinical practice.

    This goal is pursued through:

    • Acquiring knowledge on regulatory terms and conditions (mainly) in EU countries
    • Collecting input and expertize from all stakeholders in health care
    • Exchange with regulatory agencies (e.g. EMA, FDA) and health care providers
    • Initiation of collective pan-European initiatives to work jointly towards approval and reimbursement of liquid biopsy approaches
