My doctor's nurse said normal thyroid range is between 0.3 and 5.1. My thyroid came back 7.2. I looked up those readings and I can't find those ranges listed anywhere. Are these ranges correct and if so am I hypo or hyper? They are RXing synthroid is that suitable for my thyroid results?
I expect that you doctor is off base with that conclusion. Although TSH is a pituitary hormone that is affected by many variables and thereby not a good diagnostic for thyroid, at that level your TSH and your FT4 that is low in the range are good indicators that you are hypothyroid. An even more important indicator is whether you have hypo symptoms or not. Please take a look at this listing of typical hypo symptoms and tell us which ones you have.
Was hyperthyroid (Hashimoto's), lost a lot of weight had radioactive iodine treatment, weeks later went on synthroid 25 mcg. Just had a "thyroid storm", level was 7.5. Had bad episode of toxicity and ended up in the hospital. Put me on 50 mcg of synthoid and feeling better. Is this common?
