I got a gallon donor certificate in the mail one day, and a registered letter from them the next day saying they couldn't take my blood any more. They said that I had an elevated level of Hepatitis B anti-bodies in my blood and that I needed to see my physician immediately. My Dr. ran all kinds of blood work and said there was nothing at all wrong with my blood, but 20 years later I'm still on their "bad blood" list.
