Effect of Blood Donation on Blood Pressure, Iron Metabolism, Oxidative Stress

Prospective Observational Study on the Effects of Blood Donation on Blood Pressure, Iron Metabolism and Oxidative Stress

The investigators want to investigate the effects of blood donation to blood pressure, to iron metabolism and oxidative stress.

There are results of other studies that show, that there is a positive effect of blood donation to high blood pressure, iron metabolism and oxidative stress.

The regular application flow of blood donation at that blood bank of Charité is not disturbed. There are only some more questions and measurement of blood pressure, iron metabolism, fat metabolism and oxidative stress.

No extra puncture of the vein is necessary.
