Diagnosis typically involves several methods to confirm the presence of H. pylori. These include:
Urea breath test: A non-invasive test that detects the presence of H. pylori by measuring carbon dioxide in the breath. Stool antigen test: Detects H. pylori proteins in the stool. Blood test: Checks for antibodies against H. pylori, though it is less commonly used due to its inability to distinguish between past and current infections. Endoscopy with biopsy: Invasive but definitive, involves taking tissue samples from the stomach lining to detect the bacteria directly.
