welche blutwerte bei müdigkeit testen — what can you do yourself?

When experiencing persistent fatigue, certain blood markers can provide initial clues. Common parameters include: complete blood count (anemia), ferritin (iron stores), vitamin B12, folate, vitamin D, thyroid function (TSH, fT3, fT4), inflammatory markers (CRP), and fasting glucose. What you can do yourself: Maintain a balanced diet, ensure adequate sleep, regular exercise, and stress management. A self-test (e.g., home kit) can offer orientation but does not replace medical evaluation. Many factors like sleep quality, mental stress, or infections are not captured by blood tests alone. Always have abnormal results interpreted by a doctor. Caveat: blood values are only one piece of the puzzle – fatigue often has multifactorial causes.
