welche blutwerte bei müdigkeit und erschöpfung — what symptoms are typical?

The question about which blood values to check for fatigue and exhaustion is clinically important, but the provided context (DNA tests) does not directly address it. Typical symptoms of fatigue include persistent tiredness, lack of energy, difficulty concentrating, reduced performance, sleep disturbances, and emotional exhaustion. In clinical practice, common lab tests for unexplained fatigue include: complete blood count (for anemia), ferritin (iron deficiency), vitamin B12, folate, vitamin D, TSH (thyroid function), CRP (inflammation), electrolytes, kidney and liver function, and sometimes glucose/HbA1c. A DNA test cannot replace these blood measurements. Evidence strength varies: iron deficiency is strongly supported, vitamin D moderate. Fatigue can also stem from psychological or sleep disorders. Without a medical history and physical exam, lab results alone are insufficient. This answer is based on clinical practice, not on the DNA context provided.
