Measurements of Body Iron Excretion of Healthy Adults
Body Iron Excretion of Healthy Adults as Measured by Isotope Dilution
This is an observation study of subjects who previously had iron-55 isotope administered in studies of iron absorption. By determining the retention of the isotope in blood during a 3-year period, body iron excretion can be measured.
One year following initial administration of iron-55 as a part of other related studies, subjects provide blood samples every 6 months for 3 years.
