This test measures the levels of Helicobacter pylori (H. pylori) antibodies in your blood.
H. pylori are bacteria that can invade your gut. H. pylori infection is one of the major causes of peptic ulcer disease. This happens when inflammation caused by the bacteria affects the mucus coating of your stomach or duodenum, the first section of your small intestine. This leads to sores on the lining and is called peptic ulcer disease.
This test can help your healthcare provider find out whether your peptic ulcers are caused by H. pylori.
