Indications and ongoing research on
breath test are rewiewed. H2- and 13Cbreath
test are both increasingly used in
paediatric gastroenterology. In current clinical
practice the main indication for H2 -BT
is lactose intolerance, while 13C-BT is currently
used only for diagnosis of Helicobacter
pylori infection. Available evidence on
new indications (small bowel bacterial
overgrowth and research in clinical nutrition)
are also presented and discussed.
Breth test technology is relatively simple,
non-invasive, safe and accurate. Therefore
their use schould be encouraged.
