Our Serum PT offer is expanding: discover the advantages of lyophilized materials for the stability of your results
Serum is one of the most delicate and challenging matrices in veterinary analysis. Its biological nature makes it very sensitive to enzymatic degradation and temperature changes. These factors can damage the analytes during transport and affect the accuracy of your results.
For 2026, Progetto Trieste – Test Veritas announces a series of exclusive Proficiency Tests (PT) dedicated to this matrix. These tests allow international laboratories to check their performance on parameters that are very hard to find elsewhere on the market.
Guaranteed Stability: the advantage of lyophilized materials
Our main strength is the supply of lyophilized materials which, thanks to their high stability, allow for an even more reliable Assigned Value. For delicate matrices such as serum, Test Materials are provided in lyophilized form (to be reconstituted before analysis) to guarantee maximum stability, even during long-distance international shipments.
In this way, every participant, no matter their country, will receive the sample in the exact same conditions as the other laboratories. This ensures a fair and rigorous performance evaluation.
