FIN Donor 10 000

In 2015-2017 Blood Service carried out an iron study which investigated the effect of blood donations on blood donor health.

The FinDonor cohort has helped the FRCBS to understand the effects of regular blood donation to iron stores of blood donors. As shown in other Western European cohort studies, the FinDonor cohort also shows that regular blood donation does not endanger iron stores of blood donors and blood donors generally considered their health to be excellent (Lobier et al. 2019, https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0220862). Young females typically have low iron stores as was also detected in this study. In addition, a general description of the cohort has been published (Lobier et al. 2020, https://onlinelibrary.wiley.com/doi/10.1111/vox.12856). A study of change of health in FinDonor cohort participants showed that even healthy active donors should maintain their iron stores and follow FRCBS iron supplementation recommendations (Palokangas & al 2021, https://onlinelibrary.wiley.com/doi/10.1111/vox.13104). Recently, FinDonor measurements we used to study the relationship of inflammation marker CRP and ferritin (Turkulainen & al 2023, https://onlinelibrary.wiley.com/doi/10.1111/vox.13515). As CRP and ferritin are correlated, use of a minimum ferritin value in blood donation is likely to enrich persons with low grade inflammation among future donors.

Donation interval is the single most important factor affecting iron stores in blood donors, our research shows.
