Darmflora MIKROBIOM-Test | Kinder: which blood markers matter?

A gut microbiome test for children analyzes stool bacterial composition and can provide insights into diversity and imbalances, but it is not a medical diagnostic tool. Which blood markers matter depends on the clinical question: for suspected inflammation, CRP (C-reactive protein) may be relevant; for iron deficiency, ferritin; for food allergies, IgE (true allergies) – IgG tests are not recommended. Vitamin D or zinc levels can also be considered in gut-related issues. Important: blood markers alone do not replace medical evaluation. The evidence for such home tests is mostly marketing-driven or unclear; they can serve as orientation but not diagnosis. For children, caution is paramount: stool and blood self-tests should never replace a pediatrician's assessment. The provided sources do not specify blood markers for the microbiome test in children.
