HLA-DQ2 and HLA-DQ8 Gene Test for Celiac Disease
More than 95% of those with cealic disease test positive for either HLA-DQ2 or HLA-DQ8. Testing the HLA-DQ genes can be use to support the diagnosis of cealic disease, however, can also be used as a functional marker when determining if gluten products can be added back into the diet. Here are some senarios:
| Gliadin IgG + IgA Antibodies: POSITIVE TtG + Endomysial Antibodies: HLA-DQ 2 and/or 8: PERMENTIALY REMOVE GLUTEN |
Gliadin IgG + IgA Antibodies: NEGATIVE TtG + Endomysial Antibodies: HLA-DQ 2 and/or 8: PERMENTIALY REMOVE GLUTEN |
Gliadin IgG + IgA Antibodies: POSITIVE TtG + Endomysial Antibodies: HLA-DQ 2 and/or 8: PERMENTIALY REMOVE GLUTEN |
Gliadin IgG + IgA Antibodies: NEGATVE TtG + Endomysial Antibodies: HLA-DQ 2 and/or 8: PARTIALLY REMOVE GLUTEN |
Gliadin IgG + IgA Antibodies: NEGATIVE TtG + Endomysial Antibodies: HLA-DQ 2 and/or 8: ALLOWED GLUTEN |
What’s Being Tested:
- HLA-DQ2 Gene (alpha and beta subunits)
- HLA-DQ8 Gene (alpha and beta subunits)
Fasting: No
Specimen: Blood (Draw Location | How It Works | FAQs)
