What thyroid meds are you on? Those results look like you are on either NDT or T3 only? Whatever you take, your FT3 is way too low and will be causing symptoms.
All your nutrient levels are good although your B12 has dropped. Are you supplementing and changed dose?
Did you change your dose of B12? Is it a sublingual methylcobalamin?
Have you ever been on a dose of Levo or Levo+T3 where you felt well?
Your FT4 is below range and even though I take a Levo/T3 combination I still need FT4 to be near the top of the range, about 75%, I couldn't function with it low in range. Plus I need FT3 at around 75% of range.
Well you obviously didn't need your Levo reducing.
Had more bloods in feb
TSH 0.01
Freer thyroxine 14.6
Free t3 5.9
As I was still unwell he increased t3 to 40
Are those the results when he lowered your Levo from 75mcg to 50mcg? If so, and if the ranges were the same
FT4: 14.6 (12.9 - 22.0)
then there was no need to reduce your Levo, your FT4 was already low in range and now you have plummeted to below range. You probably still have some conversion and by lowering your Levo, you have less T4 so there is less to convert and you ended up with a reduced FT3 as well.
That’s what I was thinking. I might increase Levo and see what happens . The best I felt was years ago with the lovely dr s had me in 200 t4 . Such a shame he died
Your ferritin is above range for a female. Raised levels can indicate iron overload (hemochromatosis), infection or inflammation. I'd recommend seeking further advice from your GP to be on the safe side. Are you taking iron supplements?
What time was your blood test taken? Your cortisol would be on the lower side if it was done first thing for example.
The cortisol result isn't dangerously low but I don't think it rules out adrenal insufficiency at that level from a 9am test. My endo discharged me at a similar level but the lab comments even state "levels below 450 do not exclude adrenal insufficiency".
Perhaps push for a Short Synacthen Test, they are straightforward.
Yes indeed, SlowDragon is correct about the timing. When having blood tests the last dose of Levo should be 24 hours before blood draw, last dose of T3 should be 12 hours before blood draw. Any longer and you get false low results, taking too close to blood draw gives false high results.
Also do all thyroid tests as early as possible in the morning, no later than 9am, and fast overnight - water allowed, delay breakfast until after the blood draw.
All these are patient to patient tips that we don't discuss with doctors or phlebotomists.
So if planning to retest on Monday morning (for example) then you take last Levothyroxine the Sunday morning. And the last T3 dose about 8pm the evening before .....assuming blood test is 8am the following morning
Your FT4 is still likely too low, but FT3 may be perfectly fine
Ok . I may have to tell them I missed my dose . I’m even doubting when I did take it - if it was Sunday or Monday . Just been so poorly head all over the place - I seen to be getting one thing after another .
I had terrible blurred vision this morning and flashing . Optician says eyes fine . I went back to bed and woke up ok .
I seriously think something is being missed . Thanks for your help .
