Quality and Accreditation

All agrochemical studies are recognized/monitored by CGCRE/INMETRO* according to Good Laboratory Practices (GLP).

NSF Bioensaios is also ISO/IEC 17025 accredited by CGCRE/INMETRO* and holds additional accreditations from Ministries of Agriculture (MAPA) and Health (ANVISA), SENASA (Argentina) and SENAVE (Paraguay).

Toxicological Alternative Methods

NSF Bioensaios is working to implement alternative methods to traditional in vivo toxicity studies.
The strategy is based on in vitro, cell cytotoxicity, cell culture and other methods.
