Are you interested in a particular PT line? Find out more about our strenght for each line:

– Veterinary Drug Residues (pages 3-16 of our programme):

Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones). The semi-quantitative (< or >) and qualitative screening results receive evaluations provided with dedicated criteria. The quantitative screening and confirmatory results are evaluated through z-score.
More reliable assigned value due to more stability of Test Materials. Most of them are provided as lyophilized (to be tested after reconstitution). In this way, regardless of the provenience of the laboratory, every participant can be sure to receive the Test Material in the same conditions. Once reconstituted it is the same as in your routine!
In 2024 we offer many different matrices for Veterinary Drug Residues: muscle (swine/bovine/turkey/hen/chicken/rabbit), liver (sheep/bovine/swine), gut, eggs, urine (bovine/swine), bovine milk, bovine serum, fish, shrimps, medicated and non-medicated feed, and light honey.
Mainly multi-contaminated materials are provided. Several molecules of the same family or several families will be present in the same PT.
In some cases, the participation provides 2 different Test Materials, (they can be both contaminated or one of them could be blank). In the PT, as in the routine, the laboratory technicians do not know if they are testing a contaminated or a blank material. In this way, the laboratory could be assessed also for False Positive results or for method performances at different levels of concentrations.
Information about False Positives is provided in the Final Report.
Whenever possible we provide incurred (naturally contaminated) Test Materials that allow to evaluate the method extraction capability.
2024 niche PTs: M4411 for nitrofuran metabolites in gut, M4306 for ethinylestradiol in muscle …and much more!

– Freshness parameters (page 9 of our programme):

Convenient fee: 2 Test Materials for histamine are included. You will be evaluated at different concentrations levels with only one subscription! So, with our PT the convenience doubles: you will receive 1 Test Material with High Level of Histamine and 1 Test Material with Low Level of Histamine.
Furthermore, it is possible to submit 2 sets of results: with just one subscription you can evaluate 2 laboratory technicians, or 2 different techniques. Both results will be evaluated in the Final Report. So, for histamine you can send up to 4 results!
Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones).

In this way, regardless of the provenience of the laboratory, every participant can be sure to receive the Test Material in the same conditions. Once reconstituted it is the same as in your routine!
For Histamine incurred (naturally contaminated) Test Materials are provided to allow method extraction capability evaluation. For Biogenic Amines, incurred Test Materials could also be provided.
You will find: T4400 for Histamine (2 levels) and T4401 for Biogenic Amines.

– Mycotoxins (pages 22-24 of our programme):

Mainly natural multi-contaminated materials are provided. Incurred (naturally contaminated) Test Materials allow to evaluate the method extraction capability.
Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid. Even if you are using a screening method, the PT simulates what you would do in the routine (comparing your results with confirmatory ones). The semi-quantitative (< or >) screening results receive evaluations provided with dedicated criteria. The quantitative screening and confirmatory results are evaluated through z-score.
In 2024 we offer many different matrices for Mycotoxins: cereals (maize flour, wheat), nuts (peanuts), green coffee, milk, apple juice and feed.
Niche PT: WH4705 ergot alkaloids in wheat.

– Acrylamide (pages 23 of our program):

Real process contamination Test materials (not spiked) The laboratories must prefer this kind of Test Materials instead of spiked ones, to evaluate the method extraction capability.
Separate evaluation data for screening and confirmatory methods, with the assigned value deriving only from quantitative confirmatory results. This feature of our PTs respects the requirement of UNI CEI EN ISO/IEC 17043:2010 to use fit-for-purpose methods of evaluation, makes the assigned value more reliable and the assessment more valid.

In general, our Proficiency Tests for Pesticide Residues have a very conspicuous list of molecules under study. A minimum number of molecules will be present. the presence will be guarateed and declared for some of the molecules under study. Don’t forget to check our programme to know the declared molecules, it will be updated soon!
