Depends on what is meant by it being "clear" and what country you are in.
Did the doctor actually give your wife the levels of TSH and T4? The TSH is the thyroid stimulating hormone, and when the T4 (the thyroid level) drops, the TSH is increased by the body to try and stimulate the thyroid gland to produce more T4.
I can't remember the exact levels that are used, but as an example of the confusion behind what gets diagnosed as a thryoid issue or not... in the UK, if the TSH level goes above 6.0 then you are considered (other tests permitting) to have an underactive thyroid, and if it's under 6.0 then you're considered to be within normal range. (something like 3.0-3.5 is the average normal level). However, in the United States, they use the same
scale as the UK, but people in the range 4.5 to 6.0 are considered to have a thyroid issue that can still benefit from treatement, even though it's less severe. So, as you can see, someone in the UK whose 'borderline' or 'just under' the UK threshold level can be told there's no thyroid issue, whereas the US would be treating the same person as if they had a slight thyroid issue. There's no real consistency or agreement worldwide. How do I know this? I was borderline, and told it wasn't a problem but to have it checked again a month later to be sure. I read up on it to find the difference in 'opinions' in the medical community, and discussed it with my doctor, who agreed to try treatment to see if it helped.... and it did.
So, if you don't know the thyoid levels, speak to the doctor and ask what they are, and then research it yourself, bearing in mind that if it is borderline or just over etc. doesn't necessarily mean that the issue is related to thyoid as there are other tests to be done first. Including getting a T3 level check, and other tests for checking out the lump, especially as an underactive thryoid doesn't necessarily mean there will be a visible lump in the throat.
Let us know how you get on.
