Breath hydrogen test and sucrase isomaltase deficiency.Arch Dis Child. 1983 Aug; 58(8):595-7.AD
Sucrose breath hydrogen tests were performed on 7 children with proved sucrase isomaltase deficiency. All children had raised breath hydrogen excretion. The amount of hydrogen produced and symptoms experienced increased with increasing sucrose loads. The sucrose breath hydrogen test appears to be a reliable indicator of sucrose malabsorption in sucrase isomaltase deficiency.
