This article has been cited by other articles in PMC. To quantitatively summarize and appraise the available evidence of urea breath test UBT use to diagnose Helicobacter pylori H.
We included cross-sectional studies that evaluated the diagnostic accuracy of UBT in adult patients with dyspeptic symptoms. Diagnostic accuracy measures were pooled using the random-effects model. Out of studies identified, only 23 met the eligibility criteria.
There was significant variation in the type of reference standard tests used across studies. Pooled sensitivity was 0. prueba de urease en aliento

Likelihood ratio for a positive test was 12 and for a negative test was 0. Meta-analyses were associated with a significant statistical heterogeneity that remained unexplained after subgroup analysis. The included studies had a moderate risk of bias. UBT has high diagnostic accuracy for detecting H.
The reliability of diagnostic meta-analytic estimates however is limited by significant heterogeneity. Multiple prueba de urease en aliento are available in literature, but they reported different diagnostic accuracy estimates. We conducted systemic review and meta-analysis to explore the available evidence and provide pooled diagnostic accuracy measures.
Our meta-analysis showed that UBT has high diagnostic accuracy for detecting H.

Given the potentially preventable diseases associated with chronic, untreated H. It was first isolated by Warren and Marshall in It induces chronic inflammation of the underlying mucosa.

Many invasive and non-invasive methods can be used to diagnose H. Given the user-friendly, non-invasive features of UBT, this detection method may be preferred in many clinical settings. However, to date, the performance characteristics of UBT have been inconsistently described and remain incompletely defined.
