The efficacy of disinfection systems can easily be tested through microbiological analysis, or simply using buffers to check for the presence of microorganisms on the surfaces being tested. However, accurately verifying the quantity of microbial load found on a surface, in air or in water before and after treatment requires laboratory tests, such as HACCP.
In the case of chemical disinfectants, manufacturers indicate preventive tests under their disinfecting capacity; Light Progress has also carried out important tests at university and accredited Sinal (Accredia) laboratories. Of course, for both chemical disinfectants and UVGI technology, in order to obtain the same results as the laboratory, the product must be used according to the descriptions given in its instructions for use.
