Faeces for Helicobacter antigen

Detection of Helicobacter pylori antigen in faeces. Infection with H. pylori leads to inflammation of the stomach, which has a strong correlation with chronic gastritis, ulcers of the stomach and duodenum, and gastric carcinoma. This test is performed once a day (Monday-Friday). The sensitivity of the test is reduced by recent antibiotics, proton pump inhibitors or bismuth compounds. A negative result does not exclude the possibility of H. pylori infection. Turn around time 2-3 days.
