Test Results

[Datibeem]

Does my daughter need to see an thyroid doctor based on these test results?

May 2006
TSH  1.02 (.35-5.50)
FT4   .54 (.56-1.66)


October 2006
TSH .83 (.35-5.50)
FT4 .58 (.56-1.66)

She is suffering from depression and I just wanted to rule out any thyroid concerns.

Thank You.

the FT4 is lowish -- check the Ft3 - if normal, then unlikely a concern -- if low, then see an endocrinologist to eval for the unusual secondary hypothyroidism (sluggish TSH release from pituitary)

Just my 2 cents here, but I would take her to a endocrinologist for a full panel as some else suggested.  I've found that I don't feel well unless my numbers are in the mid to upper range of the t4-t3. (Those #'s may be a little different for everyone as far as feeling your best). The t3 is another important number because it tells how well her body is converting the t4 into a usable form.  So, I'd at least look into it a bit further.  If you are hypo, you certainly can feel depressed and sluggish.  M.

you should also have her free t3 tested....
just a personal observation, even though her tsh looks good her free t4 is very low and i bet her free t3 is too if she is depressed.....
you might try to get the dr to let you do a trial and see if it helps....
i know for myself if my free #'s are low i get really moody and depressed....

take care

I agree about the F/T - 3.  F/T -3  is important in how it relates to the other two. Without it, its hard to know what is the true nature.  I'd suggest that she be very carefully monitored on a regular bases by doctor because she seems to be headed towards thyroid.  In some thyroid issues the F/T-4 will react last or slower to where it will eventually end up. Some hypos will be hyper before going into full hypothyroidism and the same with hypers.  Some will become hypo before going into full  hyperthyroidism.  They do say a low F/T-3 is in depression, however mine is in the upper Labs reference range and I am considered depressed  and on meds. So I don't believe that is a 100% law.

If the F/T-3 is high, in the upper Lab range, then to me she warrants treatment.

Take her to an endo who sees and works with a lot of thyroid patients each year.

Good Luck!
