Eat your green veggies! Have a steak every now and then, for goodness’ sake!” We’ve been telling blood donors things like that for decades, but is that advice really helpful? Dr. Jed Gorlin explains the recent, troubling data on iron and blood donors.

Jed Gorlin, MDIn recent years, several excellent studies have demonstrated pretty clearly that blood donors have limited iron stores, and that the process of blood donation impacts those stores pretty dramatically. This is particularly true in several very well-defined groups of donors, including: Frequent whole blood donors (males donating more than three times in a year, females more than twice per year), premenopausal females, and young donors (especially teenagers) of both sexes. In the United States, donors may give blood every 8 weeks (up to 5 or 6 times per year), and up until 2016, males and females had the same qualifying hemoglobin (12.5 g/dL, or 125 g/L) to determine their eligibility (NOTE: The U.S. threshold was adjusted upward to 13.0 g/dL for males in 2016). Many other countries are more restrictive, and the topic of iron status of our blood donors is a very “hot” one right now!

So What do we Do?

This is an extremely important discussion, as blood centers everywhere are struggling with decreased collections. It is tempting to depend on donors in certain “easy to collect” groups, and those include donors at high risk outlined above! So, what to do? Dr. Gorlin has been heavily involved in these discussions, and he brings a unique perspective to this interview. He describes the relevant studies (linked in the “Further Reading” section below), and walks us through the steps that blood collectors (and donors) should take right away.
