Ttg Test Seems To Be Dependent Upon Lab

In my never ending desire to understand all these tests more, I was suprised by the following article: https://www.celiac.com/st_prod.html?p_prodid=1070

Based on most of my readings, I thought the tTG test to be pretty specific and sensitive. According to this article, it seems to be very lab dependent. They did the blood test at the same time they had the biopsy confirm results. This is what they found:

The average tTG sensitivity overall was 71% with a specificity of 67%. In patients with total villous atrophy sensitivity was as high as 92%, and in those with only partial villous atrophy it was as low as 38%. One of the four laboratories tested samples from 48 of the patients and their sensitivity was only 51%, while the specificity was 100%.

The final conclusion of the article:

According to these results it appears that tTG testing—at least outside of the clinical study setting—may not be accurate, and its accuracy depends heavily on which lab is used.

I am getting more confused than ever after reading this.

      Worsening vision 🕵🏽‍♀️

      By trents · Posted

      Vitamin A is important for vision health. But be careful in supplementing it as it can lead to toxicity. Research it and consult with your medical professional. I do not have a definite answer to your original question but I was pursuing the possible cause of nutritional deficiency. But your visual deterioration could be unrelated to your celiac disease so don't rule that out.

      Currently 19. Doctors think I was 1 year old when celiac started, but I wasn't diagnosed until 18, because they didn't do lab work on minors. I've been on a strict gluten-free diet for 14 months now. For example only certified gluten-free nuts and I've researched best brands a lot. I take B vitamins, vitamin D, vitamin C, Curcumin with black pepper, black sesame and green tea extract, magnesium, iron, and a little selenium and zinc, beef liver capsules. I recently had my vitamin and mineral levels retested and D is the only one I don't have enough of now. I had my eyes tested at 17 and they were good back then.

      Awaiting dermatitis herpetiformis confirmation following biopsy

      By Scott Adams · Posted

      Not everyone with dermatitis herpetiformis needs to avoid iodine. DH is caused by gluten exposure, but iodine can worsen or trigger flares in a subset of people, especially when the rash is active or not yet controlled by a strict gluten-free diet. Some people react to iodized salt, seaweed, shellfish, or iodine supplements, while others tolerate normal dietary iodine without problems. In most cases, iodine restriction is individualized and often temporary, not a lifelong rule for everyone.

      Questions: How old are you now? How long ago were you diagnosed as having celiac disease? Do you practice a strict gluten-free diet? Are you taking vitamin and mineral supplements to offset the nutrient malabsorption issues typical of celiac disease and if so, can you elaborate on what you are taking?

      My vision was good as a teen and now has gotten worse in the last year. Could that be caused by my celiac disease?🤓😎🥸👓🕶️
