How are malabsorption syndromes diagnosed?
The diagnosis of malabsorption consists of a number of different tests to look for the various causes. Generally, an endoscopy is performed under mild sedation, at which time a biopsy can be obtained for analysis under the microscope. In addition, blood tests are helpful to determine if a malnourished condition exists. Stool collections and cultures are useful, as well as certain breath and hormone tests.
