Life Length – the world leader in telomere measurement

As an independent predictive biomarker for many diseases, our proprietary Telomere Analysis Technology® (TAT®) supports clinical decision-making in early detection and risk stratification of disease.

Life Length is world leader in telomere and telomerase measurement and diagnostics, offering a range of customized services through our different technologies. We are the only company in the world able to offer a highly scalable technology to measure individual telomeres chromosome by chromosome at the cellular level from both blood and tissue samples.

Life Length is Spain’s only U.S. Federally certified laboratory under the Center for Medicare and Medicaid Services (CMS) as a “CLIA” laboratory with CLIA license 99D2112462 and also accredited under ISO 15189, recognized in more than 60 countries as well as holding the Platinum Accreditation of the American Association for Laboratory Accreditation (A2LA) and by the Spanish Government (Consejería de Sanidad de la Comunidad de Madrid) with License of Sanitary Activity CS34966. You may see copies of our licenses and accreditations here: Life Length Clinical and Diagnostic Regulatory Licenses and Accreditations

Life Length also provides in the context of our clinical assays in telomere biology related consulting services in the fields of biotechnology, pharmaceutical research and development, laboratory testing, diagnostics, and pharmacogenetics as well as in the field of cosmetics.


Our clients include physicians and clinicians working in functional and personalized/preventive medicine; corporate clients across multiple industries for R&D, product development and clinical trials; and academic researchers in scientific investigation and studies.


Life Length was founded in September 2010 as a spin-off of the Spanish National Cancer Research Center (CNIO).


Telomeres are structures at the ends of chromosomes whose main function is to act as “caps” to protect genes in process of cellular division. Each time a cell divides a portion of the telomere is eroded slightly (a phenomenon known as the “end-replication problem”). When the telomeres reach a critically short length, cell division stops and these cells enter replicative senescence or apoptosis, and eventually die.


Critically short telomeres contribute to the onset of chronic and age-related diseases including heart disease, Type 2 Diabetes, some cancers, among other pathologies.





Proprietary technology that quantifies telomere length individually (in blood samples and from cell culture)



Patented methodology telomere length is determined in tissue samples (biopsies)



Telomeric Repeat Amplification Protocol provides highly sensitive measurement of telomerase activity (in blood samples and from cell culture)



Terminal Repeat Fragmentation reports absolute telomere length using southern blot analysis of fragmented genomic DNA



Quality Polymerase Chain Reaction can be performed in samples where only DNA is available
