UBT for Evaluation for HP Eradication

The ¹³C-UBT detects current infection and can confirm the eradication of HP. UBT is used to evaluate eradication therapy after giving anti H. pylori regimens. The sensitivity is quite good in post therapy and it may be explained by the fact that the UBT gives positive results when other biopsy based tests fail. It is sensitive enough in detecting the infection even in cases of moderate colonization or patchy distribution of H. pylori.

The recommendation for H. pylori eradication is the use of UBT. The test should be taken at least 4 weeks after the patient has finished taking the eradication therapy.

UBT has a high accuracy rate in patients who have undergone gastrectomies or have recently taken antibiotic or proton pump inhibitor therapies, in contrast to serology or stool antigen tests.
