thyroid results advice please

[mistygrey]

Hi

I’m on 100mcg t4 per day and 2.5mcg t3 per day.

recently had blood tests and they showed my FT4 is at 30?

Why would my FT4 be higher than normal? I’ve been having occasional racey heart however I am diagnosed hypo and hashimotos. I can’t understand why my FT4 has gone higher.

my TSH is 0.66 so that’s normal for me, I didn’t manage to get a recent FT3 reading however I’m due repeat bloods in 3 weeks so will ask for that then.

Any ideas why my FT4 is going slightly higher above the range and what I can do with my dosage above to try and rectify this? The range is up to 28 for FT4.

Many thanks for any advice

You have hashimotos. You could be experiencing a hashis flare which would mean a rise in hormone levels.

that’s true. I’ve also been having pain under my neck right side glands not sure if I’m just under the weather or it’s a hashimotos flare as you say. Having bloods retested soon again and getting another ultrasound on thyroid in the new year via my Endo

presumably test was early morning and last dose levothyroxine 24 hours before test

Do you always get same brand levothyroxine at each prescription

when were vitamin D, folate, ferritin and B12 last tested

What vitamin supplements are you currently taking

hi yes always same brand of T4 and T3 annoyingly I stupidly forgot and took my T4 before my bloods that morning however I only took them around an hour before blood test, so I doubt they’d have been through my system that quickly to effect bloods. I took my last T3 dose at 5pm the day before however.

Both Ft4 and Ft3 definitely would show as high if you took them before test

So it’s falsely high result

[mistygrey in reply to SlowDragon]

even after an hour of taking them? Thank you that’s a relief then, I didn’t think they’d just jump up high (the FT4) for no reason. Do you know possibly why I’d be experiencing pain in my glands in my right side of my neck? Could this be thyroid related? My endo has mentioned an ultrasound scan in the new year waiting for an appointment to just check things out for me. But last time I had one I had a benign nodule that required nothing further. This was a few years ago now.

yes hormones can be absorbed rapidly into blood

Push for ultrasound in New Year

what do you think the neck pain could be? Oddly I had this same neck pain when I was first diagnosed 6 years ago and it went away when I was medicated properly with thyroid hormones
