I don't think donating your own or another match donor's works. I had surgery last year, thank goodness I didn't need blood. But I was told if someone donates blood for you, it just goes into the pool and then you get whatever comes out of the pool. There's no way to get that specific blood. Yeah, you can demand. They will tell you to go jump. I hope it's different where you are. I said then some smart person needs to start a company offering clean blood for those who need it.
