101年度食品中動物用藥多重殘留檢驗之能力試驗

101年舉辦實驗室對於食品中動物用藥多重殘留分析檢驗能力試驗，測試樣品係以牛奶為基質，參與測試之實驗室包括7縣市衛生局及13家民間實驗室。測試結果除以Robust-Z值進行判定，│Z│≦2為滿意，2＜│Z│＜3為應注意，│Z│≧3為不滿意外，動物用藥加值0.1-1 ppm時，測試結果介於添加值之70-110%範圍內者判定為「滿意」；介於60-70%或110-120%範圍內，判定為「應注意」；超出此範圍之測試結果，判定為「不滿意」。動物用藥添加值0.01-0.1 ppm時，測試結果測試值介於添加值之70-120％範圍內者判定為「滿意」；介於60-70%或120-130%範圍內，判定為「應注意」；超出此範圍之測試結果，判定為「不滿意」。各項動物用藥判定標準係以Robust-Z或回收率擇優者為評定結果。評列為「滿意」有12家（60.0%），「應注意」有2家（10.0%），「不滿意」有6家實驗室（30.0%）。本次參加之實驗室為TFDA認證項目者共計4家，評列為「不滿意」有1家實驗室。評列為「不滿意」之實驗室，除提供矯正報告，並以盲樣檢體進行複測後已完成改善。透過本次能力試驗，不僅了解絕大多數實驗室對動物用藥多重殘留分析之檢驗能力表現，也提供實驗室間檢驗技術能力比較之機會，可作為實驗室持續改進其品質管理系統之參考。

A proficiency testing was held in 2012 on veterinary drug residues (multiresidue analysis) in food. Milk were used as the testing material. A total of 20 laboratories participated in the test. The analytical results were analyzed using Robust-Z into three grading categories as follows: |Z| score ≤ 2 as ＂satisfactory＂, 2 ＜ |Z| ＜ 3 as ＂acceptable＂ and |Z| ≥ 3 as ＂unsatisfactory＂. Results of spiked experiments should demonstrate between70-110% recovery for analyte concentrations between 0.1-1 ppm as ＂satisfactory＂, 60-70% or 110-120% recovery as ＂acceptable＂, ＜ 60% or ＞ 120% recovery as ＂unsatisfactory＂; and between 70-120% recovery for concentrations between 0.01-0.1 ppm as ＂satisfactory＂, 60-70% or 120-130% as ＂acceptable＂, ＜ 60% or ＞ 130% as ＂unsatisfactory＂. Choice of better grade were made based on Robust-Z or recovery. Among the laboratories evaluated, 12, 2 and 6 were graded as satisfactory, acceptable and unsatisfactory, respectively. Laboratories graded in the category of ＂unsatisfactory＂ were mandated to provide a report of correction, as well as were requested to take a second test. Laboratories are expected to consistently improve their quality control system through this proficiency testing routine.
