Measurements of Body Iron Excretion of Healthy Adults
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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.
Condition or disease
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.
