Case studies: iron

Case studies: iron.

Iron biomarkers were developed to define the size of iron stores and the adequacy of the iron supply required to meet functional needs. Approximately 80% of the iron delivered to tissues through the circulating plasma pool will be incorporated into hemoglobin. Consequently, with the exception of serum ferritin, iron biomarkers are measures of iron sufficiency for erythrocyte production. They ha...

Studies in Iron Absorption

P REVIOUS STUDIES showed that general systemic factors like the hemoglobin concentration, serum iron concentration, iron binding capacity, and the plasma iron clearance rate were not correlated to the intestinal iron absorption. Neither did parenteral iron treatment normalize high iron absorption.1 The purpose of the present study is to examine such local intestinal factors as the quantity and ...

Interpreting iron studies.

A 63 year old woman visits her doctor with a three month history of fatigue and generalised joint pains. Her medical history is unremarkable and she reports no recent stress, infection, or weight loss. There are no abnormalities on clinical examination. Haemoglobin, creatinine, and electrolytes, liver enzymes, glucose, inflammatory markers, and thyroid function tests are normal. Ferritin, iron,...

Intravenous iron-dextran: studies on unsaturated iron-binding capacity.

A method is described for measuring the plasma unsaturated iron-binding capacity in the presence of very high concentrations of iron as iron-dextran. The procedure utilizes (59)Fe to label the apotransferrin with subsequent separation of ionic iron from transferrin-bound iron on an ion exchange or Sephadex G.25 column. The unsaturated iron-binding capacity has been measured in rabbits and dogs ...
