Hello Simran,
Welcome to the forum,what i can conclude is that your daughter can be thal intermedia,bcoz thal majors can't live without transfusions for as long as two years,though a DNA test would give you a clear picture,personally i think hb of below 8 is not good for growing age kids,though i would say hb of 10 would be very good, but since intermedias mostly maintain hb between 6 to 8,most probably their body can manage with that low hb,how about your daughter's growth,is she growing as normally as any other kid of her age,any bone deformations? (God Forbid),if not you'll have to monitor her hb on regular basis,i don't know why didn't you check her hb after transfusion,you should have check her hb after first transfusion,and follow that for how long she maintains her hb,now before going for third transfusion plz check her hb,and you can try a medicine called "hydroxyurea". It's meant for inducing feotal hb thus increasing hb level with out any transfusion,we have a member "Manal" on this forum who's son is using Hydroxyurea ,though results are a bit slow but his hb is atleast stable if not increased.
It seems like "RODEX" did work for some of the patients on this forum,you can give it a try also,but think about hydroxyurea also,and PLZ monitor your daughter's hb regularly.She can lead a normal life if you'll take right steps at right time, and without transfusions.
Take care,
ZAINI.
