I know many of you post asking for guidance on where your labs should be - and here on this forum we speak from what's best for "us" personally as well as trying to find medical documents to back us up - but in reality - it all comes down to how "YOU" feel when dialing in dose replacement.


Below you will find my most recent lab work.


I have been on 125mcg Unithroid and 7.5 mcg morning dose and 5mcg 1pm dose of lilothyronine ( aka Cytomel generic)  At first I had some flux in my lab's but looking back - I seemed to have the same movements taking brand Cytomel so the whole "generic" med's have alot of variables is a hunk of bunk.


Labs my doctor is completely satisfied with...


TSH  <0.008  ( .440 -4.670

Free T-4  1.39  ( .82 - 1.77)  ((1.29 - 1.53)) 1/2 - 3/4 of range  mid range 1.408

Free T-3  3.48 ( 2.3 -4.20 )   ((3.25 - 3.72)) 1/2 - 3/4 of range  mid range 3.4875


This is simply to prove T4 means absolutely nothing so if your doctor is using T4 lab results to dose you tell them to jump in a lake.


My doc orders a package T4, FT4 combo and then a separate T-4 , despite several notifications by me his lab is duplicating useless tests and charging me.


So can anyone explain what this means?  How about absolutely nothing!!!!


If " a T4 test is used to evaluate thyroid function and diagnose disease" - how in the world is it so low with "perfect lab results"??  This was quoted from a  reputable online lab site - and I;m sure the same words are written in the medical journals our doctors are trained from.


T4  6.8  ( 4.5 - 12.0 ) 

T4  5.5  ( 5.8 - 12.2 )   Same test name - different test manufacturers - blood drawn exact same moment.

Free T-4 and Free T-3 are absolutely necessary to properly dose yourself.
My experience is that 1/2 - 3/4 of range is your goal for optimal treatment

My Journey... 7 years to receive a diagnosis. TT 2004 after 4.5 years on Tapazole that had to be adjusted monthly - endo ran labs every 4 weeks. Remission was never going to happen for me so I opted for surgery to remove. Final DX by surgeon was Hashitoxicosis, TPO antibodies over 2000 and TSI 316% within the year prior to surgery. I never had a ultrasound or any lab testing to rule out cancer - pathology was negative. Post surgery I was kept hypo for many years - until I figured out how to dose my self, relying on where I fell in the FT-4 and FT-3 labs. I run TSH below range due to positive TBII antibodies. Horrible time adjusting to addition of Cytomel = patience pays off when adding this drug to the mix.

The happy ending ---> Stable dose since 1/10 Unithroid 125mcg, Cytomel 12.5mcg - labs I can live with.
