Interesting that some of you weren't allowed to donate due to CF. As far as I knew, the only problem the Red Cross would have with us is the antibiotic. Typically that lets me out, and now I do zithromax, so there's no way.
However, once when I was antibiotic free they did let me donate. I happened to mention it to my mother, and she was not happy with me, saying it could have a negative impact on my health.
Finally I asked my ID doctor her opinion, and she didn't think it was a good idea for me anyway.
I was contacted repeatedly after donating since my blood is O+, and they really wanted it. It made me sad as I like the idea of doing it because it seems like a way to help others with medical needs.
It doesn't matter now anyway since I have no windows of "antibiotic-free" time. I'm just surprised that some people were told they couldn't regardless of antibiotic issues. Perhaps that's been a development since I donated a number of years ago.
