Test used to determine if you have eradicated H. pylori after treatment?
a) Urea breath test (UBT), which detects the presence of H. pylori by measuring carbon dioxide levels in the breath after ingesting a urea solution.
b) Stool antigen test, which detects H. pylori antigens in the stool sample.
c) Endoscopy with biopsy and histological examination to directly visualize and assess the presence of H. pylori in the stomach lining.
d) Serological tests measuring antibodies to H. pylori, although these are less commonly used due to their inability to distinguish active infection from past exposure.
