what do these test resulta mean?

[nicobella]

I was diagnosed with graves disease (hyperthyroid) about 4 months ago and was taking tapazole and a beta blocker for treatment. After periodically checking my hormone levels they are now
T4 4.5
TSH 2.0

My doctor took me off the tapazole totally.
Does this mean I am hypo now?
I am confused.
Will my levels come up a little on their own now??

What are normal levels anyway?

Thanks.

Nicobella,
Welcome to the forum. Do you have your test sheet, so that we can know the normal ranges? Also give the complete name or abrev. of the test because I wasn't sure if that T-4 was the "Free T-4" or Total T-4 etc...
Your TSH looks like good range because the new reference range is 0.3 to 3.0, although most labs still show it to be 0.5 to 5.0. Your TSH doesn't look to be too low, so as to cause hyperthyroid symptoms. Grave's usually only turns into hypothyroidism, when you have the thyroid removed or oblated (destroyed by radio-active iodine).
These are just patient opinions and a Dr. would better be able to advize you.
Give us more detail if you can on the labs.

Thanks for the quick response. I am not too sure about my full labs. HOwever I do know the doctor meant T4 not free t4. They never really gave me anything to look at. whenever I had blood taken they just called me the next day and said....looks god or looks low or still high..so on. I had to ask what the levels were and even still they don't go too much into detail. Guess they feel I have no idea what they mean. Anyway. I have noticed that i am more tired. lethargic and constipated than usual. SO i was afraid of going hypo. I hate the thought of gaining weight and having a slow metabolism. I eat good and exercise daily...when i feel good. Oh well. TIme will tell.
thanks.

nicobella,
This is just a suggestion but I would ask for copies of every lab that is run because you pay for them and by law, you have to be provided a copy when you request it.
As I said before, I'm not a Doc but the only time I have heard about someone going from "hyper" to "hypo" but haven't had their thyroid oblated, is when they have Hashimoto's Thyroiditus. This is what most of us on this forum have and is the most common cause of hypothyroidism. It too, like Grave's, is an autoimmune disease that can cause you to swing back and forth between hyper and hypo for a while until progressive hypothyroidism takes over. The hypo usually becomes the more prominent, after the "antibodies" have caused enough damage that the thyroid can no longer spurt back to life.
Did they do antibodies tests? You might consider asking them for those past labs, they can tell you a lot and help you research.
I don't think it's common but there have been patients mistakenly diagnosed with Grave's, who actually had Hashimoto's. I have read thier testimonies. This MAY NOT be the case with you but I would sure look into those lab results.
