The main objective of REBLAS - Brazilian Network of Analytical Laboratories - is to render laboratory services related to prior analyses, pertaining to fiscal control and guidance related to products under the Sanitary Surveillance regime.

The network comprises official and private laboratories authorized by the Brazilian Sanitary Surveillance Agency (ANVISA), by means of qualification awarded by the General Office of Public Health Laboratories (GGLAS/ANVISA), and/or through accreditation by INMETRO (National Institute of Metrology, Normalization and Industrial Quality).

REBLAS provides highly reliable services with respect to analytical results, and complies with the basic tenets of analytical quality management and Good Laboratory Practices.

The prior analyses for registration of products, when they are not ruled by specific legislation, and the guidance analyses may be carried out by laboratories within REBLAS. The fiscal analyses, when subject to the legislation in force, must be carried out by INCQS and the Central Public Health Laboratories (LACEN´s). The latter must operate under the aegis of Federal, State, Municipal and District governments or of specialized bodies, when authorized to do so by ANVISA.

The laboratories comprising REBLAS are evaluated by GGLAS, which qualifies and confirms the technical competence of the entity concerned to carry out the studies and tests which fall within its remit. The basic aim of qualification is to ensure good quality of the services provided.

GGLAS/ANVISA will qualify the laboratories according to criteria established in ABTN ISO/IEC-17025, BPL, BPLC and ISO/Guidelines 43.
These are internationally accepted instruments guaranteeing quality of services and products. The overall aim is to establish criteria for qualifying national laboratories (both official and private) as well as to acknowledge foreign laboratories .
