Ferritin – not necessarily a reliable marker to determine iron status…

Blood cellsFerrtin is essentially a storage and transport protein molecule for iron within the body & it’s levels are used to help determine an individual’s iron status, hence haemoglobin and red blood cell counts. But low ferritin values are not necessarily indicative of low iron levels in female athletes, a study has shown. The study was undertaken by the Australian Institue of Sport to discover whether 6 female athletes who had moderately low ferritin levels, would show any changes to their blood count, reticulocyte (immature red blood cells) or iron levels when given supplemental iron by injection.

The results showed no comparable change between the control group, & the 6 athletes who received supplementation, indicating that ferritin may not always be an adequate marker to suggest impaired or deficient red blood cell production.
