The Cytosponge™ is a capsule on a string, which expands into a small sponge in the stomach. The Cytosponge™ test can find conditions of the oesophagus that are more common among people who have heartburn, reflux and/or indigestion.

When stomach acid or bile irritates your stomach, upper bowel or oesophagus, this is known as indigestion. Acid reflux is when stomach acid flows up the oesophagus. This can cause pain in the chest, neck or throat, also known as heartburn.
