<b >Hydrogen breath test</b>. SIBO can be detected using a hydrogen breath test, which involves drinking some lactulose sugar, and measuring the hydrogen or methane gas produced by bacteria in the small intestine as they metabolize this sugar. (These gases enter the bloodstream and are expelled by the lungs, where they are detected in the breath). <br />
<br />
A hydrogen breath test can be used as a differential diagnosis to determine whether a patient with IBS-like symptoms actually has IBS or SIBO; these two conditions cannot be distinguished by symptoms alone. <a href="http://www.ncbi.nlm.nih.gov/pubmed/18023092" rel="nofollow" target="_blank" >1</a><br />
<br />
<b >D-xylose test</b>. Malabsorption due to SIBO can be detected by the D-xylose test, which involves drinking D-xylose, and measuring levels in the urine and blood; if no D-xylose is found in the urine and blood, it suggests that the small bowel is not absorbing properly. <br />
