H. pylori tests detect whether you have H. pylori infection — a major cause of stomach ulcers and peptic ulcer disease. Four tests can detect signs of the bacteria: breath (urea) tests, stool tests, blood tests and upper endoscopy tests. A positive test result means you’ll need antibiotics to kill the bacteria and clear the infection.

Urea breath test (UBT) is a qualitative and non-invasive rapid test for diagnosing infections of Helicobacter pylori (the primary cause of gastric and duodenal ulcers). Helicobacter pylori is a fastidious bacterium known to be a potent producer of the urease enzyme.

幽門螺旋桿菌吹氣測試，正名為碳13尿素呼氣檢測 C13 Urea Breathe Test，是最方便快捷的檢驗幽門螺旋桿菌的方法。 您需要先在集氣袋內吹氣，收集基本數據。 然後您需要喝下半小杯碳13幽門螺旋桿菌吹氣測試溶劑。 待15-30分鐘後，您再於另一氣袋吹氣，便能知道結果。 由於幽門螺旋桿菌擁有一種能夠分解尿素的酵素，所以可以將溶液中的尿素轉化為二氧化碳，透過分析吹氣中的C13二氧化碳濃度，就能知道您的胃部有否受幽門螺旋桿菌感染。 其他檢驗幽門螺旋桿菌的方 …

The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide.

尿素呼气试验（UBT）分为 碳13尿素呼气试验 （13C-UBT）和 碳14尿素呼气试验 （14C-UBT），该方法检测准确性和特异度相对较高、操作方便、不受幽门螺杆菌在胃内斑片状分布影响等优点，但在使用过程中，仍需要严格遵循检测流程，以确保检测结果的准确性。 那么，13C-UBT和14C-UBT同样为呼气实验有哪些区别，在临床中如何选择？ 首先，二者区别在于呼气试验目前有两种示踪剂，即13C-尿素和14C-尿素。 13C为 稳定同位素，无辐射作用，但价格较高。 …

The urea breath test (UBT) is a test for diagnosing the presence of a bacterium, Helicobacter pylori (H. pylori) infection in the stomach. H. pylori causes inflammation, ulcers, and atrophy of the stomach. The test also may be used to demonstrate that H. pylori has been eliminated by treatment with antibiotics.

2024年2月23日 · Urea Breath Test. The UBT is useful for both the initial diagnosis of H. pylori (test-and-treat strategy) and the evaluation of post-treatment eradication of infection. Urease is not present in mammalian cells, and its presence indicates urease-containing microbes.

2021年6月4日 · Urea breath test (UBT) This test examines your breath for the presence of Helicobacter pylori bacteria, which can cause gastritis (inflammation of the mucous membrane of the stomach) or ulcers in the stomach and small intestine.
