That's an unusual pattern. Listed cause: lab interference, certain drugs such as amiodarone or heparin, T4 medication, resistance to thyroid hormone, TSH secreting pituitary adenoma.
Barb's answer is on the money. Until one doctor finally gave me the full thyroid panel which included antibodies, it wasn't diagnosed. TSH alone won't tell the whole picture. When it gets beyond the 'normal' values (which too many Dr's just focus on), that's usually when they may do more tests. Even then, you'll probably have to push for a full thyroid panel (w/antibodies labs).
The last test was last week they tested my testosterone, pituitary gland, and cortisol along with TSH and t4. And the same result came back again. High TSH and t4 and my doctor think it's my pituitary gland. But she's taking a long time to call me back about it.
In trying to assess your status, a "high TSH and T4" is not nearly descriptive enough. In addition, symptoms are much more important to making a tentative diagnosis than test results, unless TSH is extreme. So please post your actual test results and reference ranges shown on the lab report. Also, please list all symptoms yu have.
It would be really helpful if you could post your actual lab results, along with their corresponding reference ranges as shown on the lab report. This would help us better assess your situation. Typically, high TSH is related to low thyroid hormone levels (T4 and T3). Do you know if the T4 was Free T4 or Total T4? If the report doesn't specify "Free" T4, then it's Total and not as helpful. Were there any other tests performed at the same time?
It would also be helpful if you could list the actual symptoms you have so we can get an idea as to whether you're displaying symptoms of having too much thyroid hormones or not enough.
Are you currently taking any type of replacement thyroid hormone medication?
