Methane breath tests and blood sugar tests in children with suspected carbohydrate malabsorption. [PDF]
Carbohydrate malabsorption and subsequent gastrointestinal symptoms are a common clinical problem in pediatrics. Hydrogen (H2) and methane (CH4) breath tests are a cheap and non-invasive procedure for diagnosing fructose and lactose malabsorption (FM/LM)

Breath Tests for the Non-invasive Diagnosis of Small Intestinal Bacterial Overgrowth: A Systematic Review With Meta-analysis. [PDF]
Background/Aims Small intestinal bacterial overgrowth (SIBO) diagnosis is usually based on non-invasive breath tests (BTs), namely lactulose BT (LBT) and glucose BT (GBT).

Modification of baseline status to improve breath tests performance [PDF]
Breath tests used to evaluate carbohydrates malabsorption require baseline H2 and CH4 levels as low as possible. Test cancellation is recommended when exceeding certain cut-offs (H2 ≥ 20 ppm and CH4 ≥ 10 ppm).
