Objective: This study assessed the noninvasive 13C-acetate breath test (13C-ABT) as a reliable and reproducible method to evaluate gastric emptying in infants

Methods: Gastric emptying was measured simultaneously by scintigraphy and 13C-ABT in 11 infants with clinical symptoms of gastroesophageal reflux to validate the method compared with the gold standard. Gastric emptying was also measured with 13C-ABT in a separate group of 14 healthy infants on 2 consecutive days to evaluate reproducibility of the method. Half-emptying times obtained with scintigraphy and 13C-ABT were correlated with Pearson's analysis.
