Thyroid question

Free t4 is different but here is a good source. www.thyroid.ca/clinical_diagnosis.php

My most basic understanding of it is the following:

Most of the T4 and T3 circulates in the blood bound to protein, while a small percentage is free (not bound). Free T4 is not affected by protein levels and is the active form of thyroxine. The free T4 test is thought by many to be a more accurate reflection of thyroid hormone function and, in most cases, its use has replaced that of the total T4 test. Also, the T-4 testing is testing for the hyper of the thyroid.

Have you been diagnosed with a Thyroid problem already? Due to pregnancy I have to get tested every 4 weeks now my levels have been coming back with in the normal range and my t-uptake has come back a bit higher this time around, my endo said due to pregnancy that is normal and as long as my other levels are with in range we are all good.

Your TSH and other levels are in a good range and if your not seeing an Endo the general Dr will probably not do anything. However; if your not already diagnosed I would think that there is no harm in asking to take the test again in a few months to see if there is a change in your other levels.

Oh and I have Hashimoto's thyroiditis which is an autoimmune disorder so even after my levels came back ok with the Endo she was able to do a blood test for Hashimoto's which gave me my "official" dx.

No, but I've suspected I might have a thyroid problem. I have really bad fatigue issues, had a sleep study and the doctor wants to test my thyroid (among other things).

Yesterday I found out my PCP did a full blood panel when I went in for stomach issues last April and these are the results.

Would the high T4 be indicative of a problem? Also my T3 uptake is at the very lowest of the range...is that bad?

It's really hard to say if it's indicative of a problem.

My "story" is that I never realized how bad my fatigue issues where, I was a bit depressed, had a toddler and I was having a hard time adjusting after a cross country move. So for me when I started having issues with my thyroid I didn't really know and chalked it up to being other things. However; during a routine yearly physical my levels (all of them) came back completely out of range. I was tested again with in a month from the Endo Dr and ironically they were all with in normal range, so apparently my body was coming out of being hyper. So based on the results a month before she did another blood work up that showed I had Hashimoto's and even with out med's for a few years my levels came with in range.

I don't see any harm in having the Dr test again. Also, do you know if anyone else in your family has any thyroid issues, including cousins? I'm the only one with Hashi's however; several of my cousins have Graves and my paternal grandmother had a different autoimmune disorder which is a genetic link to me having an autoimmune disorder.
