welche blutwerte bei erschöpfung und müdigkeit — what can you do yourself?

For exhaustion and fatigue, common blood markers include ferritin (iron stores), vitamin B12, vitamin D, TSH (thyroid), complete blood count (hemoglobin), and in men, testosterone. These can indicate deficiencies or dysfunctions. However, home tests (e.g., for ferritin or testosterone) are less accurate than lab draws and cannot replace clinical diagnosis. A single low value is insufficient – inflammation can raise ferritin, and testosterone fluctuates daily. What you can do yourself: prioritize sleep, a balanced diet (iron, B12, vitamin D), exercise, and stress management. If fatigue persists, see a doctor to rule out medical causes. Evidence for self-tests is weak; they serve as screening, not diagnosis.
