timing for labs with T3 question

[shoenut]

Hello all,
I have a question concerning my labs. I take 25mg levothroxine (bedtime dosing)
and 30mg Erfa three times daily (90 Erfa).
The morning of labs I took one 30mg Erfa exactly 4 hours before labs. Did this produce a true picture of my T3, or was it a false reading because of the peak????

25 levo  90 Erfa been on 3 months

TSH .02
FT4 .95 (.59-1.61) 35%
FT3 5.62 (2.77-5.27) 111%
Nothing stands out as far as symptoms with this much T3 that should be happening with too much T3. Tired, achey, low blood sugar issues, some hand trembles......same old same old.

I have never taken any med before labs...I take it on my way out of the pathology lab with a bottle of water.
I remember when I was first put on thyroxine,....I would be like a strung out junkie going for labs lol...waiting to take the T4 med 'hit' but for 2 years, I have always had labs done 'naked' so to speak...NO Meds.

Thank you thelma201,
This is what I have learned as well, then somewhere my thyroid brain determined that I should know what my highest T3 level would be......but I forgot the part about it possibly being a "false reading". (thwacking forehead).

the Endo i used to see sent a reminder letter when it was time for blood work and it said "if you take thyroid medication, do not take it on the morning of the blood test"..so i go by that now, even though i don't see that doc anymore. and i take T4 only...hope this helps some :)

Hey thanks for your response, there seems to be a big controversy.....what to do.  I wonder where we find the absolute answer.
On to more research.

i have always read not to take your t3 until after the draw due to false higher t3
