GSI offers several diagnostic tests that can be completed quickly and cost-effectively in our office. These office-based tests include:
Capsule Endoscopy: A procedure that uses a tiny wireless camera to take pictures of your digestive tract. A capsule endoscopy camera sits inside a vitamin-size capsule you swallow. As the capsule travels through your digestive tract, the camera takes thousands of pictures that are transmitted to a recorder you wear on a belt around your waist. The images saved on the recorder are transferred to a computer with special software that strings the images together to create a video. Your doctor watches the video to look for abnormalities within your digestive tract.
Hydrogen Breath Test: A breath test used to diagnose bacterial overgrowth or intolerances to lactose, fructose, or sucrose. After drinking a solution of lactose, fructose, or sucrose in water, you will be asked to breathe into a small device. Your breath samples will be analyzed for hydrogen or methane content to determine if you are properly breaking down the lactose, fructose, or sucrose or if you have bacterial overgrowth.
BreathTek Test: A breath test used to test for H. pylori (Helicobacter pylori), an infection caused by bacteria in your stomach. You will be asked to breath into a small collection bag. You will then be asked to drink a solution before breathing into a second bag. If your test shows you have H. pylori, you may be given a treatment of antibiotics. After taking antibiotics, your breath test may be repeated to see if the antibiotics helped.
