wieviel eisen bei haarausfall — can a DNA test help?

Can a DNA test help with hair loss due to iron deficiency? The short answer is no. DNA tests measure genetic predispositions, not current iron levels. To assess iron status, you need blood tests such as ferritin, serum iron, and transferrin saturation. Some DNA tests may include variants related to iron metabolism (e.g., HFE for hemochromatosis) or androgenetic alopecia (e.g., AR, EDA2R), but there is no strong evidence linking specific genes to iron-deficiency hair loss. Clinical guidelines recommend checking ferritin (below 30 ng/ml is a risk factor) and thyroid function in cases of diffuse hair loss. A DNA test cannot replace these lab tests. It might provide additional context, but the evidence is weak. Always consult a doctor before taking iron supplements, as excess iron can be harmful.
