H. Pylori Antibody Test

One-in-three Americans and almost half of the world's population carry Helicobacter pylori in their guts. Among those infected, 10-20% face the risk of stomach ulcers. But about 1-2% have the lifetime risk of gastric cancer. With an easy-to-collect finger prick sample, this H. pylori antibody test checks for IgG antibodies due to past or current infections.

Typical symptoms of an active H. pylori bacteria infection include bloating, burping, nausea, bad taste in mouth, unusual stomach pain that's worse when empty or few hours after eating, and in rare cases vomiting and blood in stool.
