The National Malaria Reference Laboratory (NMARL) is a public health laboratory facility established by the Ministry of Health (MOH) with the mandate to offer reference malaria services and oversee all quality assurance programs in malaria diagnosis. NMARL operates within regulatory standards set by Kenya Medical Technicians and Technologist Laboratory Board.

NMARL provides a comprehensive range of services which are: evaluation of new Laboratory methods for malaria diagnosis, quality assurance (slide rechecking and provision of malaria proficiency tests panels), molecular diagnosis, competency assessment, formulation of policy guidelines, and inter laboratory networking.
