Helicobacter pylori is a microorganism that affects 50% of the population worldwide. A study with a non-experimental, correlational, and cross-sectional design was carried out to determine the association of the results of diagnostic tests for H. pylori infection through biopsy obtained by upper endoscopy and surface antigen test in samples of feces in 100 patients. These ones were treated at the Gastroenterology Service of the Ambulatory Surgical Clinic Center (Hospital del Día) Efrén Jurado López of the Ecuadorian Institute of Social Security (IESS), in the city of Guayaquil, Ecuador, during 2019. The mean age in the study sample was 37.5 years old, with a predominance of the female gender (78%). 65% of stool antigen tests for H. pylori were negative. The reports of the stool antigen test and histopathology allowed to appreciate differences between them, but with a predominance of the coincidences in the positive diagnoses. There was a statistically significant association between the inflammatory lesions of the gastric mucosa because of chronic atrophic gastritis and the infection by H. pylori. The results of the two diagnostic tests had a positive and weak linear correlation with statistical significance.
