Depends: On who you ask. Most lab reports show normal as being 0.5 - 5 mlu/l, but many people feel the range should be 0.3 - 3. If you are being treated for hypothyroidism, the ideal range is 1 -2. I usually start to take notice when someone's TSH is >2.5. See http://www.Nlm.Nih.Gov/medlineplus/ency/article/003684.Htm.

It's just a number: Lab results are just numbers, and numbers don't mean much without the whole picture of the patient. A TSH level of 3.30 can be normal, can be low, or can be high, depending on what is going on with the patient and on why the test was done. If the patient has no symptoms that could be related to the thyroid gland, then a TSH of 3.30 is likely normal.

Probably yes: Look at laboratory reference intervals. Tsh 2-3 is normal but if you have additional questions go see your doctor.

What is a normal range for TSH levels?

0.4–4.0 µIU/mL: However, the upper limit may be slightly too high, with several studies showing TSH above 2 may be associated with increased risk of hypothyroidism later in life. This is the normal range for adults. It is different for children.
