Preparations by which infection with H. pylori can be quickly detected while eliminating the effects of urease-producing bacteria occurring in organs other than the gastrointestinal tract (i.e., oral cavity, throat, etc.) without any fear of the detection of false positive. Namely, preparations for detecting infection with H. pylori by the urea expiration test wherein a core composition, which contains at least a C isotope-labeled urea, a filler and a lubricant at a definite ratio, is surface-coated with from 0.1 to 10% by weight, per 100% by weight of the core composition, of a coating. |
