Self Test Celiac Disease: a rapid home test that detects the presence of anti-tissue transglutaminase IgA (tTG-IgA) antibodies, common markers of celiac disease.|| How it works:| Disinfect your fingertip.|| Take una drop of blood with a sterile lancet.|| Place the sample in the test cassette.|| Add reagent.|| Wait about 10-15 minutes and then read the result.|| | Interpretation of the result:| Una single control line → negative result (antibodies not detected).|| Two lines (control + test) → positive result (antibodies detected → possible celiac disease).|| No control line or only test line → invalid test → repeat.|| | When to use it:| In the presence of symptoms such as abdominal bloating, diarrhea, weight loss, fatigue, or unexplained anemia.|| If you have a family member diagnosed with celiac disease.|| If you have associated autoimmune conditions (e.g., thyroiditis, type 1 diabetes).|| Only if you are regularly consuming gluten: una gluten-free diet can alter the result.|| | Advantages: rapid test, easy to perform at home, useful as an initial screening to assess the possibility of celiac disease.|| Limitations:| It is not a diagnostic test: a positive result requires confirmation with laboratory tests and, if indicated, intestinal biopsy.|| Possible “masked” false negatives in case of selective IgA deficiency.|| It does not serve to detect non-celiac gluten sensitivity or wheat allergy.||
