What Repeat Diagnostics does

Repeat Diagnostics Inc (RepeatDx) is a privately held clinical diagnostic laboratory headquartered in North Vancouver, British Columbia, Canada, with a secondary European office in Aachen, Germany. Founded in 2005, the company specializes exclusively in clinical telomere length testing using proprietary Flow FISH (Flow Fluorescence In Situ Hybridization) technology, which was developed and perfected by co-founder Peter Lansdorp and his team at the BC Cancer Agency's Terry Fox Laboratory. RepeatDx is the only clinical laboratory accredited to provide telomere length analysis in all 50 US States and Territories under CLIA certification, with additional licensing in Canada (BC DAP program), Europe (ISO 9001), and multiple US states (California, New York, Rhode Island, Pennsylvania, Maryland).

The company's core product is a clinical testing service that measures telomere length across six cell types in peripheral blood (lymphocytes, granulocytes, T-cells, B-cells, and NK cells), using an age-adapted reference database built from over 800 healthy subjects aged 0-100 years. Testing services address dyskeratosis congenita, pulmonary fibrosis, bone marrow failure syndromes, myelodysplastic syndromes, acute myeloid leukemia, liver failure, and bone marrow/stem cell transplant donor screening. Tests are ordered exclusively by licensed physicians through the company's website, samples are shipped to the laboratory for analysis, and results are returned to the ordering physician. RepeatDx does not bill insurance directly; billing is sent to the medical institution or patient.

Revenue is generated through one-time per-test fees (pricing not publicly disclosed). The go-to-market is sales-led and physician-direct, supported by content marketing (website, blog, social media on Facebook/Twitter/YouTube/Instagram), medical conference participation (e.g., Marrow Failure and Myelodysplasia Patient and Family Conference), and partnerships with Team Telomere (patient advocacy) and academic institutions (BC Cancer Agency, Uniklinik RWTH Aachen). Leadership comprises Peter Lansdorp (CSO), Geraldine Aubert (Director of Clinical Development & Research since 2011), Audi Setiadi (Medical Director, appointed 2025), Fabian Beier (Medical Advisor Europe since 2015), and Elmira Hariri. The company is privately held with no disclosed funding rounds, parent company, or M&A activity.

Products and services

• RepeatDx Telomere Length Testing Clinical Flow FISH telomere length analysis service that measures telomere length in six cell types from peripheral blood samples (lymphocytes, granulocytes, T-cells, B-cells, and NK-cells), providing diagnostic information for telomere biology disorders including dyskeratosis congenita, pulmonary fibrosis, and bone marrow failure syndromes. Tests are ordered by licensed medical doctors and processed at the RepeatDx clinical laboratory in North Vancouver, BC.
• Flow FISH Technology Platform Proprietary flow cytometry-based fluorescence in situ hybridization (Flow FISH) technology used to measure telomere length at the individual cell level, offering higher accuracy, sensitivity, and specificity compared with qPCR methods. Published in Nature Protocols in 2006 by Peter Lansdorp and colleagues at the BC Cancer Agency Terry Fox Laboratory.
• Dyskeratosis Congenita Telomere Testing Specialized telomere length analysis with established clinical sensitivity and specificity for diagnosing dyskeratosis congenita (DC), an inherited bone marrow failure syndrome categorized as a telomere biology disorder. Used by physicians to support diagnostic and prognostic decisions for DC and related conditions.
• Pulmonary Fibrosis Telomere Testing Telomere length analysis service used for the diagnosis of familial and idiopathic pulmonary fibrosis, disease course prediction, transplant-free survival assessment, and post-transplant immunosuppression guidance. Leukocyte telomere length has been identified as an independent predictor of disease progression in pulmonary fibrosis.
• Bone Marrow Donor Screening Telomere length testing service for stem cell donor selection prior to bone marrow or stem cell transplantation, intended to identify donors with healthy telomere maintenance. Used by physicians as part of donor selection screening workflows.

Quantifiable outcome

• Flow FISH is more accurate, reproducible, sensitive, and specific in measurement of human leukocyte telomere length compared to qPCR (peer-reviewed study published in PLOS ONE)

• Laboratory Corporation of America (LabCorp): Major national reference laboratory offering telomere length testing among many specialty diagnostics. Competes via scale and integrated billing rather than scientific specialization in telomere biology.

Direct peers

• Mayo Clinic Laboratories: Major US reference laboratory that offers telomere length testing as part of its specialty diagnostics menu. Direct competitor in the telomere testing niche, with the advantage of in-network insurance billing and broader hospital relationships.
• Johns Hopkins Genomics: Academic medical genetics laboratory offering telomere-related diagnostic testing for dyskeratosis congenita and related disorders. Comparable academic-affiliated specialty diagnostics model with research-to-clinical translation.
• ARUP Laboratories: University-affiliated reference laboratory offering specialized genetic and molecular diagnostics including telomere length testing for telomere biology disorders. Comparable niche specialty testing model with academic hospital ties.

Others

• Team Telomere: Patient advocacy organization and RepeatDx's named partner; not a commercial peer but the leading ecosystem organization in telomere biology disorders and the publisher of diagnosis/management guidelines that shape physician referral patterns.
• BC Cancer Agency / Terry Fox Laboratory: Research institution where the Flow FISH technology was originally developed and RepeatDx's co-founder remains a Distinguished Scientist. Functions as RepeatDx's R&D partner rather than a commercial peer, but shapes the technology roadmap.

Emerging players

• SpectraCell Laboratories: Specialty clinical laboratory offering telomere length testing alongside micronutrient and cardiometabolic diagnostics. Comparable specialty-lab model targeting niche clinical biomarkers.
• Life Length: Spain-based specialty telomere diagnostics company offering TAT (Telomere Analysis Technology) for clinical and research applications. Closest technology-adjacent peer competing in the same telomere measurement niche from outside North America.
