VFAD has recently participated in proficiency testing organized by Test Veritas S. r. l. (Italy), “Progetto Trieste 2014, 2nd round” for the beta-agonists (salbutamol, clenbuterol and terbutaline) group analysis (confirmatory) in swine urine (test identity: U1423/GA) by using LC-MS/MS.
22 laboratories took part in this U1423/GA test; we are 1 of the 20 with a satisfactory result of z-score: 1.08 for clenbuterol (z-score <2 represents a satisfactory result). Salbutamol and terbutaline were not detected by our laboratory as they were absent in the U1423/GA test material.
