检查幽门螺旋杆菌(Hp)的方法有细菌培养、组织学和快速尿素酶试验,但均需内镜及胃粘膜活检术。非侵入性尿素呼吸试验(UBT)及血清学检查可取代上述方法。UBT 是检查尿素酶活性有 Hp 感染活动性的良好方法。血清学方法已被广泛用于间接检查 Hp 感染。健康人50%有抗 Hp 抗体(抗-Hp),但不清楚其为活动性感染抑或只代表过去感染史。本文用血清学和 UBT 对100名健康人的 Hp 感染情况进行研究及评价。病人与方法 100名健康者,年龄20～92岁。均无慢性消化不良、溃疡病及腹部手术史(阑尾炎除外)。试验前1年内未服过抗酸剂、铋剂及其它治疗消化不良的药物。3个月内没有服抗生素。所有受试者经一夜禁食后在上午进 Bacterial culture, histology, and rapid urease tests were performed on H. pylori (Hp), but both endoscopic and gastric biopsy were required. Non-invasive urea breath test (UBT) and serological tests can replace the above method. UBT is a good way to check urease activity for Hp infection activity. Serological methods have been widely used for indirect examination of Hp infection. Fifty percent of healthy people have anti-Hp antibodies (anti-Hp), but it is unclear whether they are active or only represent past history of infection. In this paper, 100 healthy subjects with serological and UBT Hp infection were studied and evaluated. 100 healthy patients and methods, aged 20 to 92 years old. No chronic indigestion, ulcer disease and abdominal surgery history (except appendicitis). 1 year before the test did not take antacids, bismuth and other drugs to treat indigestion. No antibiotics in 3 months. All subjects entered the morning after a fasting overnight
