In brief: TSH accurate

Tsh is the most sensitive indicator of thyroid function.
If it is normal (as yours is), it is highly unlikely that you have a problem with your thyroid. There are rare problems of the pituitary gland in which the TSH is not an accurate test. In that case a free T4 level is helpful. Despite what you may read on the internet, T4 and t3 (liothyronine) levels are usually only helpful if the TSH is abnormal.
