Medichecks results

Hello all, I have just received the above thyroid test results and would appreciate some advice. I am feeling a bit underactive and wondered if I should increase my levothyroxine slightly? Thanks in advance

How do these compare to previous results?

Are you T4 only?

How are your folate, B12, Vit D and ferritin looking?

Your fT4 is a little too high which can mean slightly worse conversion to fT3 so you might actually find a small decrease perhaps 12.5mcg a couple of times a week might help

Pushing fT4 higher isn't good for you long term so it's better to add in a little T3 f your conversion isn't good enough

Vitamins are all good. I’m only on T4. I had a T3 trial and did not feel well. I was just wondering if TSH should be below 1 for people with Hashimotos.

[TiggerMe Ambassador in reply to Pinkisland]

Great that you have sorted your low B12 and folate... TSH really isn't that important when you have the free's to go on... I'd try a small reduction and test in 8 weeks

[greygoose in reply to Pinkisland]

Not necessarily because of Hashi's. But because your Free levels are high enough to make you well, and therefore the TSH is automatically lower. Your FT3 is rather low, because you are a poor converter, and the TSH reflects that.

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

is this how you do your tests?

Do you always get same brand levothyroxine at each prescription

Your Ft4 is high (levothyroxine)

If you tested correctly you possibly need to reduce dose Levo a little

[Pinkisland in reply to SlowDragon]

Yes tested corrctly...just before 9...only drank water and last dose 24 hours before. Just a bit confused becuase I have read on previous posts that people with hashimotos feel best on a tsh level below 1.

Your results show very poor conversion

Free T4 (fT4) 22.4 pmol/L (12 - 22) 104.0%

Free T3 (fT3) 4.8 pmol/L (3.1 - 6.8) 45.9%

Ft4 over range ….so you may need to reduce levothyroxine a little

Possibly low vitamin levels

Next step test Vitamin D, folate, B12 and ferritin

Are you on gluten free and/or dairy free diet

[Pinkisland]

Vitamins tested and good but going to try gluten free and see if that helps.
