I was diagnosed with Celiacs several months ago. I then had both my daughters tested since I also was positive for both Celiac genes. DQ2 and DQ8. My older daughters results showed >100 on t-Transglutaminase (tTg) IgA (o-3 is normal). She is now on a gluten free diet. Neither myself or my daughters have or had GI issues associated with Celiacs.
My younger daughter got a 4 on the same test, which is considered Weak positive. She also got the following results on Deamidated Gliadin test:
IgA 8 (0-19 normal)
IgG 15 (0-19 normal)
Her pediatrician said she does not have Celiac.
Do you agree with this? What does weak positive mean? I just wondering if I should pursue this further for her.
I wanted to add that my younger daughter started eating gluten free at home since I had been diagnosed and changed over our house. Most of her meals (but not all) were gluten free prior to being tested 2 months later. I am thinking to get her retested, but How much and for how long does she need to eat gluten to get an accurate blood test?
