13 C-尿素呼气试验 (1 3 C- UBT)是诊断幽门螺杆菌 (Hp)感染的重要方法之一。它具有无毒、无创伤、准确、快速等优点 ,但检测价格昂贵的问题一直阻碍着该方法的推广。近年来 ,研究人员在保证诊断灵敏度及特异性的前提下 ,对 1 3 C- U BT进行了多方面的改进 ,如新型价廉的检测仪器 ,低剂量 1 3 C-尿素胶囊的应用 ,试验餐的改良及检测时间的缩短等 ,降低了检测成本 ,大大推动了 1 3 C- U BT的更广泛应用。
The 13 C-urea breath test (13 C-UBT) is one of the important ways to diagnose Helicobacter pylori (Hp) infection. It is non-toxic, non-invasive, accurate, fast and so on, but the detection of expensive problems has been hindering the promotion of the method. In recent years, researchers have made many improvements in 1 3 C-U BT on the premise of ensuring the diagnostic sensitivity and specificity, such as the new and inexpensive detection instruments, the application of low-dose 13 C urea capsules, The improvement of meals and the shortening of testing time reduce the cost of testing and greatly promote the wider application of 1 3 C-U BT.
