Test Results meaning

[Blue727]

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.

Help!!

I need interpretation with the recent test results of my sister's thyroid hormones estimation....



The tests were conducted at 3 different labs and it seems they point to something which general physicians are unable to pin-point...


Tests:


1.>  Ultra TSH (using CLIA)- 19.02  (normal range - 0.4-6.02)
       T3 - 0.692   (range- 0.846 -2.02)
       T4 - 4.90     (range- 5.13 - 14.06)


2.> TSH - 70 (range - 0.17-4.05)
      T3- 130 (range- 70-200)
      T4- 6.0  (range 5.5-13.5)


3.>TSH - 77.35 (range - 0.30-5.5)
     T3  -     98     (range- 60-200)
     T4 -      5.60  (range 4.5-12.0)

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.

I am a 28 year old male, with symptoms of both hyper and hypo.  Thanks for your help!

[Mark Lupo, M.D.]

If they are all in the normal (even low-normal) range, then there is not likely any problem with the thyroid.

[kitty9309]

OOPS!

I thought this was the patient to patient forum.

[kitty9309]

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?
