One of the possible purposes of testing is for product registration at both national and biocide levels. ECHA guidelines provide binding guidance, but also require considerable flexibility due to the lack of precise instructions. Experimental protocols must therefore be designed, but for these to be accepted, they must be scientifically valid. Our ongoing research, as demonstrated by numerous publications, ensures the scientific consistency of our studies. Our experience in pest control also allows us to best reproduce the issues of field conditions during our simulated use tests. We are not active only in Europe; thanks to our flexibility and adaptability, Entostudio also provides registration studies across continents, adopting specific guidelines: ANVISA, T-CTCA, GB/T, S-CDC, EPHI, JIS, PMDA, ICMR, MFDS, ESR, SANS, NEA, US, etc.
