Helicobactor pylori: Sensitivity and Specificity
Introduction: From UpToDate (http://www.utdol.com/online/content/topic.do?topicKey=acidpep/4732 ):
The ACG guidelines made the following conclusions:
Testing for H. pylori should be performed only if the clinician plans to offer treatment for positive results.
* Testing is indicated in patients with active peptic ulcer disease, a past history of documented peptic ulcer or gastric MALT lymphoma.
The test-and-treat strategy for H. pylori (ie, test and treat if positive) is a proven management strategy for patients with uninvestigated dyspepsia who are under the age of 55 years and have no "alarm features" (bleeding, anemia, early satiety, unexplained weight loss, progressive dysphagia, odynophagia, recurrent vomiting, family history of GI cancer, previous esophagogastric malignancy).
* Deciding which test to use in which situation relies heavily upon whether a patient requires evaluation with upper endoscopy and an understanding of the strengths, weaknesses, and costs of the individual test.
