My doctor wants me to have my thyroid checked, what should I expect?

Your doctor may recommend that you undergo a blood test called a TSH (thyroid stimulating hormone) to determine the health of your thyroid. A normal TSH level is usually considered between 0.4 and 4.0 mIU/L. If your results are above or below this range, it could indicate an abnormality in your thyroid function.
