Besides, what should your TSH level be?

A normal range for TSH in most laboratories is 0.4 milliunits per liter (mU/L) to 4.0 mU/L. If your TSH is higher than 4.0 mU/L on repeat tests, you probably have hypothyroidism. Your doctor may also order a T4 test. Most of the T4 in your blood attaches to a protein, and when it does, it can't get into your cells.

What is normal TSH level in female?

The normal range of TSH levels is 0.4 to 4.0 milli-international units per liter.
