[Fwd: FT3 Calculation]

[Guest guest]

here are results:

Bj/anyone, can you please comment on the FT3/4 ratio. i know there has

been much discussion about ft3and ft 4 ratio as of late.

FT4 1.1 (0.8 to 1.8)

FT3 2.7 (2.2 to 4.0)

TSH 3.865: note this has been bouncing between 1.8 and close to 7 for

six years now and I have gone untreated. 90% of the time it is >4.

As a reminder I have been diagnosed with hashi's 7 years ago (TPO >2000)

and Bj and I have gone back and forth on whether I could possible have

Graves. My endo never answered my internist on this question and she is

sending me to a new endo.

P.S. also, as mentioned below, when FT3 is calculated the " old

fashioned " way by multiplying the two values - depending on who your

source is -- my FT3 is 105. here you go...

Thank you for any insight you have into FT3/4 ratio.

Bj ( I know you might be especially interested in this) and anyone else,

as i wrote you several weeks ago, Bj, I brought in your brilliant email

to my internist at today's appointment ie could i possibly have

graves/hashis (do you remember that email)?

what my internist (whom I adore; it's the endo I cannot stand) told me

was that the person who " invented " the FT3 and FT4 test was a doctor at

the hospital I go to in Boston. Two values are multiplied. I have to

go to my notes later to give you more details and she said that there is

controversy among the endos whether this is a better way to measure FT3

or the " straight up " FT3 test. Apparently, my FT3 last time was checked

by the multiplication of the two lab values but this time she sent in

for a straight FT3. It will be interesting to see the difference in the

two lab values.

Have you ever heard of this?

Anyway, I will give you more detail if you are interested later. I will

find the names of the thyroid values that are multiplied, etc. I am

completely overwhelmed and exhausted right now (I now have three

possible diagnoses and I feel like my head could explode).

BTW, Bj I told my internist what an incredible mother you were and how

you saved your child's life. She was very moved by this.

will tell you more later.
