<<Disclaimer: Verify this information before applying it to your situation.>> My husband's gastro doctor wants him to have a xylose tolerance test. Does anyone have any experience with this? If so, is it a good test for absorption? I'm assuming that is what it is used for in this case. The doctor indicated that his recent blood tests were "good" and indicated that the gf diet is working, but that he now wants him to have this test. (He did scare us by telling us that he must have had it for 10 years before he was diagnosed due to his low weight for many years.) Thanks for any replies! Gina
