Comparing Diagnostic Methods

ACG guidelines no longer include serology in H. pylori testing recommendations1

  • Serology is an inadequate method to test for H. pylori infection2
    • Sensitivity 85%, specificity 79%2
    • Cannot distinguish active H. pylori from past infection2

Some diagnostic labs have discontinued offering serologic testing for H. pylori3,4

Stool testing is associated with relatively low patient adherence5,6

In one study, more patients returned for a post-treatment UBT vs FAT (N=29)6

Stool Testing Post Treatment

vs

Fecal occult blood

BreathTek® UBT for H. pylori aligns with guideline recommendations to test, treat, and confirm eradication of H. pylori infection.7

ACG guidelines recommend urea breath test (UBT), fecal antigen test (FAT), and endoscopy for eradication testing.7
