摘要

前言：快速、自動的結核菌培養偵測系統BACTEC MGIT 960已在台灣廣為應用；然而，目前非結核性分枝桿菌在臨床實驗室的高分離率也造成診斷上的困擾。此研究主要目的為評估COBAS AMPLICOR MTB在BACTEC MGIT 960陽性檢體的臨床應用。
研究方法：從2006年3月1日到2007年2月28日共有270個BACTEC MGIT 960陽性檢体在台北醫學大學•萬芳醫院進行COBAS AMPLICOR MTB檢驗，並與傳統生化菌株鑑定的結果進行比較。
結果：207(76.7%)個COBAS AMPLICOR MTB檢驗有決定性結論，63（3株為結核菌，60株為非結核性分枝桿菌）個檢驗無決定性結論。在176個結果為陽性者，174個檢驗為真陽性，2個檢驗為偽陽性。在31個結果為陰性者，30個檢驗為真陰性，1個檢驗為偽陰性。若不考慮檢驗結果為無決定性結論者，此項應用的敏感性、特異性、陽性預測值與陰性預測值分別為99%、94%、99%及97%。
結論：COBAS AMPLICOR MTB可能適合作為BACTEC MGIT 960陽性檢體快速偵測及鑑定結核菌的檢驗工具。
