Less than 20 is normal. The question is, how much less are you asking about? Why did you have the test run?

AR is correct, unless you have had thyroid cancer then you *need* a TSH level of <.2.  

Undetectable or zero is the most desirable for cancer patients.

As AR asked, why did you have the test run?
