What is the normal range for TSH levels?

TSH Thyroid level of 0.246 ul/ml ?

• I asked my doctor to check my thyroid because of my unresolved symptoms that go across the board. I just received my records to check levels myself, and the only test run was the TSH. Which I understand is a good indicator. However it is well below the reference range, and even says abnormal beside it. The level was 0.246 Does this warrant further lab testing? From what I have read it could indicate hyperthyroidism, and in some cases oddly enough hypo. But I don't understand why the doctor wouldn't mention this and say everything came back normal. Is this normal even though it is well below the normal range? I would prefer other thyroid patients and medical persons, and anyone who has a good knowledge of endocrinology to reply to help me get a direction of what to do. Thank you,

  It means your thyroid is currently overactive. Your doctor should have asked you to make an appointment to have another blood test to see if it is temporary. This happened to me about 10 months ago. My thyroid was 'slightly overactive' according to a blood test and I had to have another one a week later and it was then within the normal range. I am from the UK and the normal range used by the lab is 0.5 - 5.0. I had another test in December last year and I am now diagnosed as hypothyroid and taking levothyroxine tablets so it was probably the last gasp of my body trying to normalise itself :/ Seriously, you should go back and ask for another blood test I would. Just tell the doctor you believe your TSH indicates a degree of hyperthyroidism.
