What to watch with Zöliakie Test and Darmgesundheit?

When it comes to celiac testing (e.g., HLA-DQA1/DQB1 genotyping), caution is warranted: detecting risk alleles like HLA-DQ2/DQ8 indicates genetic predisposition, not active disease. Many carriers never develop celiac. A positive genetic result alone does not justify a gluten-free diet – serology (tTG-IgA) and duodenal biopsy are required for diagnosis. For gut health tests (microbiome analysis), the evidence is even weaker: most commercial tests lack clinically actionable recommendations. The microbiome is highly individual, varies daily, and is influenced by diet. Claims about 'bad bacteria' or 'leaky gut' are often exaggerated. Look for tests with validated reference ranges and medical supervision. Avoid unnecessary dietary restrictions or supplements based on unproven results. If you suspect celiac or other gut disorders, consulting a gastroenterologist is the only safe approach.
