On Wednesday 29 July 2026, the Laboratoire National de Santé (LNS; national health laboratory) released its 2025 Annual Report, reporting a return to profit of €2.74 million after a €12.49 million loss in 2024, while annual turnover increased to €63.16 million.

The LNS 2025 Annual Report reflects on the institution's key achievements over the past year and highlights the advances that have "strengthened its role in diagnostics, public health, medical expertise and scientific support" within Luxembourg's healthcare system.

According to the LNS, the institution continued to expand its activities in diagnostics, medical expertise, research and public health surveillance while supporting the "ongoing evolution" of Luxembourg's healthcare system. Among the year's key milestones were the legal recognition of the profession of genetic counsellor, preparations to expand the national newborn screening programme through the introduction of screening for Severe Combined Immunodeficiency (SCID), the launch of Luxembourg's first national human biomonitoring survey and the installation of a CT scanner dedicated to forensic medicine.

Six flagship projects highlighted

The 2025 Annual Report places a special focus on six flagship projects, each presented through a short video in the digital version of the report:

  • Medical Biology: the introduction of newborn screening for Severe Combined Immunodeficiency (SCID), enabling earlier detection of a rare but life-threatening disease;
  • National Centre of Genetics: the digitalisation of the clinical genetics pathway through the Defgen platform;
  • National Centre of Pathology: the development of interoperability between the LNS and Hôpitaux Robert Schuman (HRS) for the secure exchange of medical data;
  • Microbiology: the detection and sequencing of the MPOX virus to support genomic surveillance of infectious diseases;
  • Legal Medicine: the installation of a post-mortem CT scanner to complement traditional autopsies;
  • Health Protection: the launch of LëtzHBM, Luxembourg's first national human biomonitoring survey.

The LNS in numbers

According to the report, the LNS employed 415 staff members representing 26 nationalities at the end of 2025. Women accounted for 65% of the workforce and men 35%, while the average employee age was 43 years. During the year, the institution recruited 41 new employees, and the average length of service among permanent staff stood at 8.21 years.

Dr Thomas Dentzer, Director of the Laboratoire national de santé: "The year 2025 fully reflects our ambition to continuously improve diagnostic and medical services and our commitment to public health. Behind each project presented in this report are dedicated teams developing practical solutions to improve diagnosis, strengthen prevention, support healthcare professionals, and address today's and tomorrow's public health challenges.”
