How Long After Eating Gluten Are The Blood Tests Accurate?

I'm about 95% sure I have celiac disease due to severe symptoms I have tested using my own dietary tests.

However, I haven't eaten gluten in about a month and I'm interested in getting a blood test to have an "official" diagnosis mainly for my parents and others who need that kind of diagnosis to feel that it is real.

Will a blood test such as the TTG and EMA be accurate even if I haven't eaten gluten in a month?

You could possibly get a false negative. Here's a link from this website:

This says the blood tests should go negative in 3-6 months, but I have heard of them going negative sooner. And it is still possible for you to have Celiac even if your blood tests come back negative!

      If you have hemorrhoids 1x weekly I don't see how you have time to heal from one episode before you experience another one, unless each one is a very minor event. Have you consulted a physician about your hemorrhoid issue? It's not normal to be having an episode every week unless it is really one episode that is not completely healing between weekly...

      No I haven't had one since 2021. I rarely have more than 1 per week.

      Sorry, I see that now as I reread your original post. You say you have hemorrhoids "only once a week" now. When I develop hemorrhoids, which is once every few years now, it generally takes 3-4 days for healing to take place. So, it doesn't seem like you could have much relief time between episodes if you have them weekly. Have you had a lower GI scoping done...

      Everyday I eat a medium to large apple in the morning and a large banana at night. I eat a cup of oatmeal in the evening. The ezekiel wheat bread I eat has a good amount of fiber. I haven't dealt with constipation for at least a year. Most of the time my feces are soft.
