Ein DNA-Test allein kann keine Fruchtbarkeitsdiagnose stellen oder die Lebenserwartung präzise vorhersagen. MyBody-X-Tests sind als Lifestyle-Produkte deklariert, nicht als medizinische Geräte. Sie unterliegen in Deutschland dem Gendiagnostikgesetz (GenDG), das für gesundheitsbezogene Analysen eine ärztliche Aufklärung vorschreibt.
