What should the T-transglutaminase Iga test result be?

t-Transglutaminase (tTG) IgA Optimal Result: 0 – 3 U/mL, or 0.00 – 100.00 ug/g. A tissue transglutaminase IgA (tTg-IgA) test is used to help doctors diagnose celiac disease or to see how well people with the condition are doing.

Can a TTG IgA be positive for celiac disease?

Tissue Transglutaminase (tTG) Antibody, IgA. Testing for tTG IgA antibodies is recommended as an initial screen to identify patients at risk for celiac disease, and in whom duodenal biopsy should be performed to confirm disease. Some patients may have positive tTG IgA but negative EMA IgA and/or deamidated gliadin peptide (DGP) IgA results,…

How big is the tTG antibody in Iga?

tTG ANTIBODY, IgA. <4.0 U/mL (negative) 4.0-10.0 U/mL (weak positive) >10.0 U/mL (positive) tTG ANTIBODY, IgG. <6.0 U/mL (negative) 6.0-9.0 U/mL (weak positive) >9.0 U/mL (positive) References:
