I have donated a few gallons in my lifetime. My child, when working in a restaurant while in college, asked me if I could suggest how her friend at work, who had no medical insurance, could get some medical testing done. I suggested she donate blood. They actually do a mini-medical exam before they take your blood. I was denied being allowed to donate a few times for being underweight, and a few times for having low iron.
