welche blutwerte bei müdigkeit — can a microbiome test help?

For fatigue, standard blood tests include complete blood count, ferritin (iron), vitamin B12, vitamin D, TSH (thyroid), and possibly inflammatory markers (CRP). A microbiome test may indicate dysbiosis, but evidence linking it directly to fatigue is weak and mostly mechanistic. Current guidelines do not recommend microbiome analysis for fatigue workup. Such tests remain experimental and should not replace medical evaluation.
