Question

Can someone with kidney disease donate blood

Answer 1

Yes because long story short you blood in this case is not contagious therefore, you can. But remember in other cases you might not be able to.

Answer 2

You can... Chronic Kidney Diseases doesn't't mess heavily with overall blood composition, neither does spread between people or is dangerous to donate. There are several instances where one may not donate blood; blood transmitted disease like HIV or Syphilis, or a clotting factor deficiency, which is hemophilia, which while not exactly anything to worry about bloodwise, is much more dangerous to the person donating it, as without proper equipment or medication, a patient can bleed out.
