Smear of duodenal fluid aspirate is an examination of fluid from the duodenum for a possible infection. Usually the health care practitioner is looking for either giardia or strongyloides. Alternative Names: Duodenal aspirated fluid smear How the test is performed: advertisement The specimen is obtained by EGD (esophagogastroduodenoscopy), a flexible scope that is passed through themouth and stomach to the duodenum in order to view the organs and obtain 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 (suctioned up)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. How to prepare for the test: Do not eat or drink anything, even water, for 12 hours before the test. How the test will feel: You may have a gagging sensation as the tube is passed, but it is usually not painful. Why the test is performed: The test is performed to diagnose infection of the small bowel. In most cases, this test is only done when stool examinations and a duodenal string test have been unable to confirm the diagnosis.
