Measurements of Body Iron Excretion of Healthy Adults

Completed

• Conditions: Healthy

• Registration Number: NCT00755105
• Lead Sponsor: USDA Grand Forks Human Nutrition Research Center

Brief Summary

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.

Detailed Description

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.
