Measurements of Body Iron Excretion of Healthy Adults
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.
|Study Design:||Time Perspective: Prospective|
|Official Title:||Body Iron Excretion of Healthy Adults as Measured by Isotope Dilution|
- Rate of Iron Excretion. [ Time Frame: 4 years ] [ Designated as safety issue: No ]Iron excretion calculated as body Fe (mg) times turnover rate estimated from blood activity of Fe55
|Study Start Date:||September 1998|
|Study Completion Date:||December 2005|
|Primary Completion Date:||December 2005 (Final data collection date for primary outcome measure)|
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.
