welche blutwerte bei müdigkeit testen — what symptoms are typical?

Fatigue is a non-specific symptom with many potential causes. Typical accompanying symptoms include lack of energy, difficulty concentrating, sleep disturbances, muscle weakness, or low mood. Common blood tests for fatigue workup include: complete blood count (anemia?), ferritin and iron (iron deficiency), vitamin B12 and folate, vitamin D, TSH (thyroid function), inflammatory markers like CRP, blood glucose (or HbA1c), liver and kidney function, and electrolytes. If sleep apnea or chronic fatigue syndrome is suspected, further specialized testing is needed. Important: A single consumer DNA test (e.g., MyBody-X) cannot diagnose fatigue; it may only indicate genetic predispositions for certain metabolic pathways. The evidence for these blood markers is based on clinical practice and guidelines, not on direct study references in the provided context. Persistent fatigue warrants a medical evaluation.
