The Laboratoire national de santé (“LNS”) is a public institution under the supervision of the Ministry of Health in Luxembourg. Organized as a multidisciplinary institute and supported by a professional services team, the LNS includes four scientific departments in the fields of medical biology, microbiology, forensic medicine and health protection, in addition to hosting the National Center of Pathology and the National Center of Genetics. The LNS has its new premises in Dudelange, with state of the art, modern infrastructure in line with recent developments in medical sciences. Its objective is to develop scientific and analytical expertise related to the prevention, diagnosis and monitoring of human diseases. Its ultimate mission is to serve patients and citizens and offer excellence in health care.

The Department Health Protection supports public health and health care for problems caused or aggravated by the environment, including indoor pollution, the working context, consumer products, food and food contact materials. We fulfill this mission through servicing, expert advice and applied research. Our main stakeholders are the ministries and the hospitals in Luxembourg.


The Department Health Protection hosts three Services:

The Service also provides scientific expertise in these domains. It is the major laboratory ensuring the protection of the human food chain in Luxembourg and takes care of multiple analyses for Saarland;
  • The Service “Environmental Hygiene and Human Biological Monitoring” carries out chemical laboratory analyses in dust and air samples (ISO/IEC 17025 accreditation) and microbiological analyses in dust, air and surface samples for indoor pollution and occupational hygiene. In parallel, the Service analyses the substances’ concentrations directly in the human medical samples (blood, urine, hair,…); known as “human bio-monitoring”;
  • The Service “Medical Expertise and Data Intelligence” hosts the medical, epidemiological and toxicological expertise as well as the European science-policy programs in environmental and occupational health/medicine. The Service supports the Hospital Center Emile Mayrisch (CHEM) in the new discipline of Environmental Medicine/Health in Luxembourg, launched 17 November 2022.
