Hi all.
I am an 18 year old male. Recently I had anti ttg-igA tested and it came back as 9.1 IU/ml (weak positive) (increased from previous test which was 5.6iU/mL) . What does this mean please? I am booked for an endoscopy however, i am negative for both HLA DQ2 and DQ8. I have a family history of coeliac.
