Is everyone 'signing up' actually checking that they
can give blood? I don't want to put a damper on a good idea but I do feel there is need for medical input & I'm no doctor.
I used to give blood regularly in UK, sometimes called in for specific donation because of an AB+ve blood group (not the rarest but relatively uncommon). Soon after moving here I got schistosomiasis (bilharzia), quickly dealt with by medication but the antibody remains in the blood for a very long time. My June tests in UK showed schistosoma antibody negative - first time in 12 years! I didn't give blood for all that time, not wishing to pass on that antibody to someone who would be confused by it showing up in their tests when they'd never had bilharzia. Now I find that some sites are suggesting don't donate if you're over 60 & haven't been a donor in the last 5 years. Other sites say 70...........
I am no expert. All I'm saying is that it is better to have people on a register who
can actually donate when the need arises. Here are some UK sites you can check: note they don't all say the same things exactly. There must be US sites as well. None of them exclude women in menstruation age range (as per comment on previous thread). However, be aware that the 'do's' and 'don't' on these links will be culturally specific to UK and may or may not apply in DR.
