Endoscopy for Giardiasis
Endoscopy is a test in which a lighted viewing tube (Reference endoscope Opens New Window) is passed down the throat (Reference esophagus Opens New Window), through the stomach, and into the upper part of the small intestine (Reference duodenum Opens New Window).
After the viewing tube is in the small intestine, it can be used to obtain a sample of the contents of the small intestine (duodenal fluid). This sample can then be tested to see if the Giardia parasite is present.
