Test Results meaning

Does having a low, but "normal" TSH, Free T3 and Free T4 mean hypothyroid, hyperthyroid or something else?  My scores have either been in the very low "normal" range or a little below the "normal" range for the last 4 years.

by Mark Lupo, M.D., Mar 25, 2008 06:04AM
If they are all in the normal (even low-normal) range, then there is not likely any problem with the thyroid.

Were all three in the low normal or below normal range?

Or just the TSH?

A low TSH is hyperthyroid.

A "normal" TSH with low free t3 or 4 could be hypothyroidism.

All 3 low could indicate: Nonthyroidal illness; Rare pituitary (secondary) hypothyroidism

Can you post your results with the reference range?

OOPS!

I thought this was the patient to patient forum.

All of the thyroid levels are good except for 1/19/08.
A TSH of about 1-2 is great!
T3 uptake isn't a test used very often. It is an older test, not as accurate.
I can't say anything about saliva testing.

      T3- 130 (range- 70-200)
