How to prepare for Gluten Test

Preparation for a gluten test depends on the test type. For a blood test for celiac disease (e.g., tTG-IgA), you must consume gluten regularly for several weeks beforehand to avoid false negatives. For a genetic test (HLA-DQ2/DQ8), no special diet is needed because the genetic risk is independent of current intake. Based on the provided context, MyBody-X does not appear to offer a dedicated gluten test; its tests focus on microbiome or DNA markers unrelated to gluten. Therefore, any preparation advice from the company is likely generic. Evidence for home gluten sensitivity tests is weak, and self-diagnosis can be misleading. Always consult a healthcare professional for proper testing and interpretation.
