Risks and limits of Gluten Test

The provided context does not contain specific information about a gluten test from MyBody-X. Based on general knowledge and parallels with other home tests (allergy, DNA, microbiome), the risks and limits are: such tests can offer clues but are not diagnostic. A gluten test might assess genetic risk (HLA-DQ2/DQ8) or antibodies (tTG-IgA), but results require clinical confirmation. False positives/negatives are possible, especially with self-sampling and lack of physician oversight. Overinterpretation is a major risk: a positive genetic marker does not guarantee celiac disease, and a negative result does not rule out non-celiac gluten sensitivity. The evidence level is 'unclear' or 'marketing' because no specific validation data for this test is provided. Caution: do not change diet based solely on a home test; consult a gastroenterologist.
