Frequently Asked Questions (FAQs) for HLA-DQ2/DQ8 DIRECT:
Q1: What does a positive result for HLA-DQ2/DQ8 mean?
A: Positive results indicate genetic susceptibility to celiac disease but don’t confirm the disease itself.
Q2: Can a negative result rule out celiac disease?
A: No, as other genetic markers and environmental factors might contribute to celiac disease development.
Q3: Is this test necessary for everyone with celiac symptoms?
A: Not always; it’s often used to support diagnosis in cases where celiac disease is suspected.
Q4: Can HLA-DQ2/DQ8 testing predict the severity of celiac disease?
A: No, it only indicates genetic susceptibility, not the severity of the condition.
Q5: Can this test determine gluten intolerance or sensitivity?
A: No, it’s specifically for celiac disease genetic markers and doesn’t diagnose other forms of gluten sensitivity.
