Hydrogen breath tests are non-invasive and safe diagnostic tools used to investigate functional intestinal disorders. For the diagnosis of fructose or lactose malabsorption as well as for the detection of small intestinal bacterial overgrowth syndrome, hydrogen breath tests are even regarded as gold standard. However, standardization of the testing procedure and the interpretation of the test results are still lacking. In this paper, reliable information on the implementation of the most common… 
Tricks for interpreting and making a good report on hydrogen and 13C breath tests.
TLDR
Among (13)C breath tests, the best and well characterized is represented by the urea breath test, and well-defined protocols are available also for other ( 13)C tests, although a reimbursement for these tests is still not available.
Hydrogen breath testing in children: What is it and why is it performed?
TLDR
How the HBT works, and why and how it is used in children is looked at, and the varying conditions detected by the test are addressed together with their treatment.
Hydrogen and Methane Breath Test in the Diagnosis of Lactose Intolerance
TLDR
The results indicate that CH4 measurements may possibly be of additional value for the diagnosis of LI, since 5.7% of patients were negative for H2 and positive for CH4, and half of them experienced symptoms during the test.
The importance of methane breath testing: a review.
TLDR
The combined measurement of hydrogen and methane should offer considerable improvement in the diagnosis of malabsorption syndromes and SIBO when compared with a single hydrogen breath test.
Delayed Analysis of Hydrogen-Methane Breath Samples
TLDR
The effect of delayed analysis of breath samples, facilitating the at-home performance of breath testing, appeared to be less reliable and expired hydrogen levels remain stable in plastic syringes if preserved at room temperature for several days.
Hydrogen–methane breath testing results influenced by oral hygiene
TLDR
Data suggest that a single mouthwash at baseline has a high probability of returning a false positive diagnosis of hydrogen–methane breath test results, and concerns that oral hygiene is not a standard inclusion in current breath testing guidelines are raised.
Lactose Malabsorption Testing in Daily Clinical Practice: A Critical Retrospective Analysis and Comparison of the Hydrogen/Methane Breath Test and Genetic Test (C/T−13910 Polymorphism) Results
TLDR
Only moderate agreement between the breath test and the genetic test was shown, indicating secondary lactose malabsorption as well as preanalytical limitations of the combined H2/CH4 breath test procedure can cause discrepant results.
No Correlation between Positive Fructose Hydrogen Breath Test and Clinical Symptoms in Children with Functional Gastrointestinal Disorders: A Retrospective Single-Centre Study
TLDR
Positive fructose HBT in children with functional gastrointestinal disorders can be attributed to their younger age but not to some peculiar clinical feature of the disease.
Prevalence of abnormal lactose breath hydrogen tests in children with functional abdominal pain
TLDR
Lactose malabsorption was seen in 58% of children with non-organic chronic abdominal pain, and twenty out of 34 children improved on lactose free diet while 8 out of 11 children of SIBO improved on antibiotics.
Hydrogen sulphide in exhaled breath: a potential biomarker for small intestinal bacterial overgrowth in IBS.
TLDR
It is shown that hydrogen sulphide (H2S) in exhaled breath is distinctly altered for diarrhea-predominant IBS individuals with positive and negative SIBO by the activity of intestinal sulphate-reducing bacteria, and the changes in H2S in the bacterial environment may contribute to the pathogenesis of SIBO.

Use and abuse of hydrogen breath tests
TLDR
Hydrogen breath tests are widely used to explore the pathophysiology of functional gastrointestinal disorders and there is extensive use of these tests in clinical practice with difficulties regarding interpretation of the tests and sometimes erroneous conclusions.
Using breath tests wisely in a gastroenterology practice: an evidence-based review of indications and pitfalls in interpretation
TLDR
Breath tests are valuable tools that are, in general, underutilized in evaluating dyspepsia and functional bloating and diarrhea, as well as suspected malabsorption, including lactose intolerance.
Hydrogen breath test for diagnosis of lactose malabsorption: the importance of timing and the number of breath samples.
TLDR
A three-sample H(2)BT is time- and cost-sparing without significant loss of sensitivity for the diagnosis both of lactose malabsorption and lactose intolerance.

BACKGROUND Small intestinal bacterial overgrowth (SIBO), which may result from intestinal stasis, is common in malabsorption syndrome (MAS). Quantitative culture of upper gut aspirate is used as a
H2 BREATH TESTS DURING DIARRHEA
TLDR
The H2 breath test is a convenient, noninvasive technology for use in children, but it cannot be recommended for measuring carbohydrate malabsorption in individuals with active, on‐going episodes of diarrhea.
Methodology of the H2 breath test. II. Importance of the test duration in the diagnosis of carbohydrate malabsorption.
TLDR
It is thought that for greater diagnostic accuracy the lactose H2 breath test must be prolonged for at least 4 hours.
Effect of predominant methanogenic flora on the outcome of lactose breath test in irritable bowel syndrome patients
TLDR
Patients with predominant fasting methane production excrete less H2 than LMP, after an oral load of lactose, and the lower prevalence of severe lactose intolerance in PMP, as well as lower incidence of symptoms during the test, is related to lower and slower H2 excretion.
Comparison of a portable breath hydrogen analyser (Micro H2) with a Quintron MicroLyzer in measuring lactose maldigestion, and the evaluation of a Micro H2 for diagnosing hypolactasia.
TLDR
For diagnosing hypolactasia, the Micro H2 appeared as reliable for measuring breath hydrogen concentrations as Quintron MicroLyzer commonly used in oral lactose tolerance tests.
