We encounter synthetic compounds in air fresheners, building materials, personal care products, and cleaning supplies that didn't exist generations ago
It is invasive, expensive, and can only sample the proximal small intestine, since endoscopy doesnt typically extend beyond the duodenum.1 This is a significant limitation since distal SIBO is thought to be most common.2 Additionally, culturing cannot accurately reflect the anaerobic bacteria present in SIBO since most anaerobic bacteria cannot be cultured.3 Similarly, organic acid testing, which can indirectly indicate bacterial overgrowth by the presence of urinary hippurate, p-hydroxybenzoate, and other bacterial metabolites, cannot distinguish the location of overgrowth between the distal small intestine and the proximal large intestine, nor offer the details provided in a breath test.4 Stool tests can only suggest large intestine bacterial overgrowth, although they can show the fat malabsorption that often results from SIBO

Indeed, great efforts have been made in the field over the past two decades to search objective biomarkers to inform the diagnosis of ASD, especially biomarkers from blood since it is easily accessible and inexpensive
