I have had Grave's Disaease for 6 years now and have always left it in the hands of my doctors. So I do not know what the labs mean. I kinda have an idea though. TSH normal levels are .350-5.0. Does hyperthyroidism occur when you are below the .350? My level results were .869 a few days ago. I know that is in the normal range, but where exactly do I fall in that range. Can anyone help me to understand this better? I just do not feel well and don't know why. If it's my Grave's Disease or something else. So any advise or links to where I can get some answers would be great! Thanks!
