Myths vs facts: Cardio Risk Check | Herz-Kreislauf Risiko-Test and Allergie

The combination of a Cardio Risk Check and an Allergy Test sounds appealing, but the evidence is limited. For cardiovascular risk, SNPs in genes like TCF7L2 or FTO are often analyzed. However, these variants have small effect sizes and are not deterministic. Lifestyle factors (diet, exercise, smoking) have a much larger impact. A DNA test cannot accurately predict risk or replace personalized therapy. For allergies, the genetic component is complex and involves many genes with small effects. Most commercial allergy tests rely on IgE measurements or skin prick tests, not DNA. A genetic test for allergies is not clinically validated and cannot provide a reliable diagnosis. Instead, established methods like skin prick tests or specific IgE should be used. Conclusion: Both tests have scientific foundations, but their predictive power for individuals is low. They should be considered as supplementary information, not as a basis for medical decisions.
