TF
TF makes transferrin, the main protein that carries iron in blood. The common rs3811647 marker has a strong, repeated association with transferrin amount and total iron-binding capacity. That association does not provide one general iron level and does not determine stored iron, iron deficiency, anemia, hemochromatosis, or supplement need.
