Blood donation and Hb (day 0)

I started my newest tiny study about what happens to blood values after blood donation. I did my blood donation at local Veripalvelu office. At that site you will find more information which is related to blood donation.

I will make Hb measurements in the morning with empty stomach about every 3rd day. First values I took in the morning (donation day), second value was taken just before donation and 3rd value just after.

I will not use any medications or any kind of extra iron sources. Although I just did a Marathon run four days ago.
