Can you find any info out on testing for this enzyme which converts T4 to
T3? Why don’t they test for it anymore. Are there any physicians lurking
who can tell us what’s going on with testing. Why only a TSH test now
if there were more tests done previously?

Dr. Arthur Prange may know; he’s on our board of directors and has done
research concerning deiodinase. This is detailed in a video from our first
conference in Berkeley, CA. My recollection is that there are 3 forms of
the enzyme and 2 work in the brain and 1 in the body or vice versa.
At any rate, I feel it should be reasonable for patients who are not
doing well on T4 only medications to be able to get a test to see if
they have this enzyme at all. It’s made in the liver and used in the
cells to convert T4 to T3.
Also, what is it’s chemical structure, possible patients with a DNA
anomoly for these enzymes cannot covert T4 to T3.
The “official” endocrine establishment fails to recognise these possibilities.
‘Oh, that can’t happen.” is what I hear.
It used to be part of a series of diagnostic thyroid tests.
Are any doctors out there lurking who know why it was stopped?
email me with answers if you don’t want to post to this board.
