The Laboratoire national de santé (LNS) is a public institution under the supervision of the Ministry of Health in Luxembourg.

Organised 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.
