We have to have our sons blood drawen this weekend and our doctor has never given us a goo time (before meds after meds) to do this. I just want to know that we are getting the right results and not good results because meds were taken too soon before draws or to close to the next dose. Does everyone have their labs done every three months? Our endo says that once a year is ok and they always come back good (so does bone age) but I asked for a blood draw to be taken now and we just had one in January. Dr said no problem.
