How to prepare for Gluten Labor

The provided context does not contain specific instructions for preparing for a gluten test (e.g., for celiac disease or gluten sensitivity). General medical practice advises continuing a gluten-containing diet before testing to avoid false negatives. Since no MyBody-X-specific guidance is given, the evidence level is 'unclear'. Caveat: Consult a physician before testing, especially if you have digestive issues. MyBody-X tests are not diagnostic and do not replace medical evaluation.
