Iron
(FE)
Material: | 10 ml urine 1 ml serum (no lithium-heparin metal tube), avoid hemolysis, avoid long venous stasis (stability in serum at 4°C – 8°C: > 14 days) 1 g biopsy specimen in sodium chloride solution |
Methods: | Spektrometrie → UV- / VIS-Photometrie | Reference range | Serum: 35 – 150 µg/dl (6 – 27 µmol/l) Urine: < 70 µg/l (< 12 µmol/l)
Children: Please refer to findings report |
Indication | Suspicion of iron deficiency, iron malabsorption or iron overload |
Please note | The iron values show severe fluctuations and evaluation is disturbance-prone. Infections lead to decreased serum levels, taking medication (estrogens, ovulation inhibitors) leads to increased serum values. To avoid misinterpretations, the additional testing of ferritin is recommended. For capturing the full iron status, apart from iron and ferritin, testing of transferrin, transferrin saturation and a small blood count is recommended. In case of an anemia as part of a chronic illness, the additional evaluation of the soluble transferrin receptor is useful.
