Thyroid

A few informative sites about thyroid issues:

"TSH rise in DS may be independent of thyroid disease. There is a transporter problem with TSH and too much of it gets made more than is needed for feedback. There seems to be no effective way to stop this but it should not cause a problem except in worrying people that thyroid disease is there. I have seen more than a few endocrinologists treat the TSH alone and have caused hyperthyroidism in more that 40 patients by doing this."

Tests for Thyroid and Related Functions        http://www.westonaprice.org/Best-Kept-Secret.html


Test Normal Range SI Units
Comments
Free-Thyroxine (T4), by Direct Dialysis method
0.8-2.7ng/dL
 10.3-34.7 nmol/L
The only accurate T4 level
Free Triiodothyronine (T3), by Tracer Dialysis 2.3-5.2ng/dL  0.035-0.08 nmol/L
The only accurate T3 level
and the only true measure of thyroid function
Thyroid Stimulating Hormone (TSH) serum level 0.3-2.5 mIU/L  0.3-2.5 mIU/L
A relative or indirect test,
not definitive of thyroid function.
Total Thyroxine (T4) serum level
4.0-12.0ug/dL
 51.48-154.44 nmol/L
Inaccurate test of pre-hormone
Free-Thyroxine (T4), non-dialysis method
0.7-1.8ng/dL
 Less accurate than dialysis test
Total Tri-Iodo-Thyronine (T3) serum level
100-240ng/dL
 Inaccurate test for T3 activity
Free Triiodothyronine (T3), Non-dialysis method
2.3-5.2ng/dL
 Less accurate than dialysis test
T3 Resin Uptake 25-39%  Primitive, inaccurate T3 test
T7 or Free Thyroxine Index/ FTI (T3U x T4 level)
1.0-4.0
 Slightly better than T3U test
Microsomal TPO Antibodies Titer
<35 units  
Organic (Protein-bound) Iodine level
8.0-16.0
 The only level that is necessary
Inorganic Iodide level 1.0-4.0
 Valuable if too high, indication to avoid inorganic iodine (iodide)
Total Iodine level 9.0-20.0
 Mixed conglomeration of the 2
Selenium serum level
140-280
 Normal level needed
Zinc level
70-150  Normal level needed
Copper level
70-150
 Make sure not too high
Mercury level
<5
 Make sure not too high
Aluminum level
<7
 Make sure not too high
