No. Analysing microbial genes involved in nutrient metabolism cannot confirm or rule out coeliac disease or lactose intolerance. Both require medical assessment and, where appropriate, specific tests, such as serology and intestinal biopsy for coeliac disease or a breath test for lactose intolerance.
Do not use your results alone to remove foods from your diet: in coeliac disease, avoiding gluten before testing can make diagnosis more difficult.
