摘　　要：目的　建立检测幽门螺杆菌感染的无损伤、无放射性方法———15N 尿素发射光谱分析法。方法　对 2 6例受检者用15N 尿素发射光谱分析法检测其幽门螺杆菌感染。结果　诊断特异性为 81% ,灵敏度为 89% ,阳性预测值为 84%。结论　该方法具有一定的实用意义。Objective To study a noninvasive and nonradioactive method, ~ 15N-urea tracing emission spectroscopy,for detecting theHelicobacter pylori(Hp) infection. Methods A group of 26 patients was tested with a method of ~ 15N-urea tracing emission spectroscopy for detecting theHp infection . Results Taking the bacterial culture or (and) Gram stain as a standard, the specificity, sensitivity and positive predicting rate of the test were 81%, 89% and 84%, respectively. Conclusion The method could be considered useful for clinical practice.
