Which of the following are diagnostic tests for Helicobacter pylori infection
Question : Which of the following are diagnostic tests for Helicobacter pylori infection? (Select all that apply)
A. Urea breath test
B. Gastric mucosal biopsy with histology
C. Serum Helicobacter pylori antibody test
D. Fecal occult blood test
Answer: ABC
Explanation: Diagnostic tests for Helicobacter pylori infection include invasive tests (gastric mucosal biopsy with histology, rapid urease test) and non-invasive tests (urea breath test, fecal antigen test, serum antibody test). The fecal occult blood test is used to detect gastrointestinal bleeding, not Helicobacter pylori infection. Hence, the correct answers are ABC.
