I think my Thyroid may be off. What is "normal" TSH?

Question

First I don't even know what TSH stands for....help. One of my doctors suggested I have blood work done to test my thyroid. The results were mailed to me, but I don't understand them. They read: TSH 1.06 [0.27-4.20] mcIU/mL Thyroid problems run in my family. What is "normal" TSH and what is considered Hypothyroidism?

Answer 1

It says right there that the normal range is    0.27-4.20   and yours is 1.06.  You are in the lower end of the normal range.

Answer 2

TSH is "thyroid stimulating hormone"

diagnosing hyper or hypothyroidism is more complex then one lab reading.  You must see a doctor.

A low TSH is suggestive of hyperthyroidism (not hypothyroidism)
