Check Sample Program

The AAFCO Collaborative Check Sample Program is a Proficiency Testing Program for analytical chemistry laboratories and consists of twelve specially ground and mixed commercially manufactured animal feed samples.  The series, which begins in January of each year, includes a variety of feeds, pet foods and supplements with nutrients, drugs, antibiotics, minerals, and vitamins at levels typically encountered in commercial products. Samples are shipped to participants each month of the year and are tested for analytes of interest by each lab.  Results for individual analytes are reported using specified AAFCO method codes and units to allow for analysis of the performance of individual methods or method types.  Reported results are analyzed statistically and participants are provided with performance scores for each analyte and method reported.  Results are used by laboratories as part of their quality control/quality assurance programs.  Extra materials from each monthly testing round are offered for purchase as Quality Reference Materials (QRMs) or “past samples”.

Laboratory data are reported using the AAFCO Check Sample Program data reporting website.  Prepared report cards and method performance reports of the consensus summary data are available for download from the AAFCO Check Sample Program data reporting website.
