ILT – Interlaboratory Test offers Microbiology proficiency testing schemes designed to assess and improve laboratories’ performance in the detection and enumeration of microorganisms.

We provide qualitative schemes, focused on the detection of target microorganisms using lyophilized strains, and quantitative schemes, focused on the enumeration of microorganisms using strains supplied in liquid vials.

All strains supplied are Certified Reference Materials (CRM), ensuring full traceability and reliability of the results. The test matrix can be shipped either separately from the strain or pre-inoculated, according to the specific needs of each laboratory and the test method used.

Statistical evaluation of results is carried out under ISO/IEC 17043 and ISO 13528, ensuring objective and internationally accepted assessment criteria
