【Abstract】 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.更多还原
