Strange results! Would value opinions.

February 2022 on 125mcg Levo

TSH 0.04 (0.27-4.2)

FT3 5.22 (3.1-6.8)

FT4 19.1 (12-22)

January 2024 125 Levo 3mcg Lio

TSH 0.0008 (0.27-4.2)

FT3 4.7 (3.1-6.8)

FT4 18.1 (12-22)

After about a year adding Lio why has my FT3 lowered ?! Seems very odd. I mean I do feel quite a bit better. Still a slump at times but I don’t need to nap in the afternoons. So do I add a little more T3 or just go back to Levo only?

My GP surgery have sent a couple of texts asking me for TFTs but I’m ignoring them at the moment and will continue to after this latest Medichecks showing the suppressed TSH.

Vit D 107 (50-250)

Active B12 93.3 (37.5-188)

Ferritin 112 (30-264)

Folate 42.9 <7

No raised antibodies (which is normal for me)

Any opinions gratefully received as always 😀

Oh Sept 2022 on 125 mcg Levo

TSH 0.1

FT3 4.78

FT4 16.7

All same range

How much T3 are you taking? I suspect its more than 3mcgs?

Free T4 (fT4) 18.1 pmol/L (12 - 22) 61.0%

Free T3 (fT3) 4.7 pmol/L (3.1 - 6.8) 43.2%

When did you take your last dose of Levo & T3 before this test and what time of day was it?

Did you remember to stop the B complex 4-7 days before the blood test?

These are your results on 125mcgs only and they look like are converting OK but could perhaps do with a Levo increase.

Free T4 (fT4) 19.1 pmol/L (12 - 22) 71.0%

Free T3 (fT3) 5.22 pmol/L (3.1 - 6.8) 57.3%

Only taking 3mcgs lio in the mornings. But the day before test took at 6pm. All bloods taken as advised here.

It’s all a bit strange isn’t it 🤷‍♀️

I’m thinking of dropping the T3 (self sourced) and adding 12.5 mcg of Levo. What do you think? 🤔

I think adding the extra 12.5mcgs Levo might make all the difference. It does look like you convert well enough so long as vitamins are optimal and that little bit more might just take you over the line.

Yup. Going to try it. I think I did one test just over a year ago where it looked like low FT3 so I thought I would try Lio. Looks like back to basics 😉thanks for your help
