Previous proficiency test results
Earlier results of our laboratory in international interlaboratory proficiency tests. The latest results (September 2026) are on the Certificates page.
We actively participate in the international interlaboratory proficiency testing schemes organised by BIPEA (France). BIPEA is one of the world's leading bodies in laboratory performance evaluation, bringing together over 2,500 laboratories from 120 countries.
During each proficiency test, we receive blind samples with unknown amino acid profiles. Our objective is to perform accurate quantitative determinations for all target amino acids.
For each individual amino acid, performance is graded based on strict statistical parameters:● satisfactory — the result is correct and within the internationally accepted deviation limits.● questionable — the result is within an acceptable boundary but exhibits a deviation slightly larger than standard.● unsatisfactory — the result is outside acceptable limits.● not assessed — this specific parameter was not measured in the round.
Throughout 2020, our laboratory successfully passed three BIPEA proficiency rounds.
In 2024, we renewed our participation in BIPEA interlaboratory proficiency tests; the 2024 report is shown below. The latest results (September 2026, programme PT 26A “Amino acids – feed”, casein sample) are presented on the Certificates page.
