<<Disclaimer: Verify this information before applying it to your situation.>> Hi list members. Well, after my panicked request a couple of weeks about regarding the prep for a sigmoidoscopy, it looks like the tests I'll be having don't involve any prep! I'd like to get any info or experiences you've had with any of the following. (I need to plan whether I can just walk in by myself or need to take someone with me.) So, did you experience discomfort, side effects, etc. after any of the following tests? - d-xylose test - Shilling's test - upper GI series Thanks! Anne p.s. These tests all involve radioactive material. I guess I'll be glowing!!!
