National Health Laboratory Service (NHLS) is a national diagnostic network based in Johannesburg, Gauteng, South Africa. It operates more than 230 laboratories and provides essential diagnostic testing for a large portion of the country's population. The organization employs several thousand people, reflecting its scale within the South African health system. NHLS collaborates with government health bodies and national programs to leverage laboratory data for public health, including partnerships with the Gauteng Department of Health and the Wits Diagnostic Innovation Hub. In 2026 it launched South Africa's National Diabetes Dashboard (HbA1c) to support nationwide monitoring of diabetes control. The organization has faced IT disruptions in recent years, including a March 2026 system failure affecting its information service, and earlier ransomware-related outages.
