Brenda44 replied to Slr38's topic in Celiac Disease - Pre-Diagnosis, Testing & SymptomsI suspect that I have celiac or NCGS. I ordered a Biocard, but since I live in America and it comes from Canada, it took weeks to get here. I had given up and went on the gluten free diet and was having good results. The test finally showed up and I decided to use it on my dad because I think he has a much worse case of it. He has eight stents in his heart, diabetes, arthritis, bruising, nosebleeds, gout, on and on and on. I did the test on him and we just sat and chatted waiting on a result. We were outside and didn't have a clock so I didn't time it down to the minute. I looked at it after a few minutes and didn't see anything. After about 10 or 15 minutes I looked and saw a very, very faint line. It is now about 4 hours later and I can still look at the test and see that very faint line. If it's positive, does the positive line tend to stay in the window for that long? I know i have a pregnancy test from 17 years ago that told me my son was on the way and it still shows positive. Just wondering if the fact that it stays there is any more confirmation that he's positive? The instructions say not to read it after 10 minutes, but if you're negative, why would a positive show up anytime after 10 minutes?
