[IPk] thyroid problems



Normal ranges... yes the lower  end range for T4 has been increased so a now
a reading of 11 would be considered as underactive thryoid when a year or 2
back it would be normal. Some doctors don't use/know about the new ranges. I
think its the same in the States for most tests, but not all. Please be
aware that T4 measurement is not the same as FreeT4 so different results are
interpreted differently.



Test
Abbreviation   Typical Ranges  Serum thyroxine T4 4.6-12 ug/dl Free
thyroxine fraction FT4F 0.03-0.005% Free Thyroxine  FT4 0.7-1.9 ng/dl  Thyroid
hormone binding ratio  THBR 0.9-1.1  Free Thyroxine index FT4I 4-11 Serum
Triiodothyronine T3 80-180 ng/dl  Free Triiodothyronine l FT3 230-619 pg/d Free
T3 Index FT3I 80-180  Radioactive iodine uptake RAIU 10-30% Serum
thyrotropin TSH 0.5-6 uU/ml  Thyroxine-binding globulin TBG 12-20 ug/dl T4
+1.8 ugm  TRH stimulation test Peak TSH 9-30 uIU/ml at 20-30 min  Serum
thyroglobulin l Tg 0-30 ng/m Thyroid microsomal antibody titer   TMAb Varies
with method Thyroglobulin antibody titer TgAb  Varies with method
The following website gives good information about all the tests and what
they mean. Note that very low TSH can aos indicate pituatory problems as
well.

I can't understand many people posting that they hope to get off thyroxine
soon.. just like insulin, another hormone, this is needed for life.. get
over it!  They are tiny tablets, best taken early morning 10-15 minutes
before other meds or food (never at night) and my 11 year old has no problem
swallowing them.. oh that diabetes would be as easy to control as thyroid
problems. It may take a while to get thryoxine doses optimised and yes when
not, they will have a direct effect on BGs, but once on the right dose you
should feel and be far healthier.

Always stick to the same brand and never break tablets in half as this is
highly inaccurate. Thryoxine comes in 25mcg, 50mcg and 100mcg, so all
combinations can be achieved.

Fluctuations, just like glucose control are normal and to be expected. When
TSH results rise, this is normally an indication of need for greater doses
of thyroxine, regardless of T4 results. 80% of T4 is converted from T3 and
T3 produced by the thyroid. If TSH levels are raised it means the thyroid is
working harder and less efficiently to produce the required amount of T3.

Hope that helps
