“A unit of red blood cells (RBCs) costs about 120 pounds”
“a donation is 0.5 units of red blood cells”
So 0.5 unit / donation * 120 pounds / unit = 60 pounds / donation
A donation takes the time to go there and get the blood out, plus the lost productivity from feeling weaker (assuming you were going to do something productive counterfactually); I don’t know what’s that number, but I’d put it at about 1 hour. So ~60 pounds / hour.
Good comment / I agree.
