How is the Test Performed?
The specimen is obtained by EGD (esophagogastroduodenoscopy), a flexible scope that is passed through the digestive tract to the duodenum for the purpose of viewing the organs and obtaining specimens.
The test may also be performed by passing a thin flexible tube into the small intestine. The position of the tube can be confirmed by the pH (acid base balance) of the fluid or by an X-ray.
Fluid is aspirated from the duodenum when the tube or the scope is in proper position. The fluid is placed on a microscope slide and stained for examination.
