H. pylori testing is used to diagnose an infection with the bacterium Helicobacter pylori in the stomach. This bacterium is a common cause of peptic ulcers and can also contribute to gastritis and stomach cancer. There are several methods to test for H. pylori infection, including:
1. Blood test: A blood test can detect antibodies to H. pylori in the bloodstream, indicating a current or past infection.
2. Stool test: A stool sample can be tested for the presence of H. pylori antigens or genetic material, providing evidence of an active infection.
3. Breath test: A breath test involves drinking a solution containing radioactive carbon or urea, which is metabolized by the H. pylori bacteria in the stomach. If H. pylori is present, it will produce detectable levels of carbon dioxide in the breath.
4. Endoscopy with biopsy: During an endoscopy procedure, a tissue sample (biopsy) may be taken from the stomach lining and examined under a microscope for the presence of H. pylori bacteria.
These tests can help diagnose H. pylori infection and guide treatment to eradicate the bacteria, typically with a combination of antibiotics and acid-reducing medications. It is important to consult with a healthcare provider if you are experiencing symptoms of stomach ulcers or gastritis to determine if H. pylori testing is needed.
