Hi Andy
Lab Test Online revealed the following:
"Does donating blood affect my iron levels? Yes. Every time you donate a pint of blood, your body loses about 250 mg of iron. The level of serum ferritin, which is a reflection of the total amount of storage iron, drops with each donation. The more blood you donate, the lower the ferritin becomes. Other tests, such as serum iron and TIBC, are not as affected by blood donation."
My daughter is going to donate 200ml of blood each time and her latest ferritin was 1724 ug/L. How many blood donating sessions she need to bring her ferritin level down to 300 ug/L theoretically?
Thank you.
Best Regards
