I just have a question regarding how low the Hb should be before transfusion. Over here in Perth, Australia, they would now transfuse my son if he is 10. He's pre transfusion Hb count is usually between 7.8-8.8. I feel that he really suffers when his Hb count drops to 8.0. He gets his transfusion every four weeks, on 375mg exjade and ferritin level is around 1300. My son plays badminton seriously. He can only join tournaments based on his transfusion date. The latest he could play properly (although I feel there is already danger in it) in a tournament was at 3rd week of transfusion. He did come 2nd on local junior tournament for singles, and first for doubles. In singles he loss to his doubles partner. His friend knew he was already low on blood and couldn't push it any further. Even his coach asked if we could bring the transfusion date forward, but we all know there is no such chance. I wasn't at the tournament, but my husband said that he thought my son had stopped breathing momentarily during the finals of the singles match. Is it advisable to let him continue with the sport?
