Bit confused about blood results

[Arlie123]

Hi everyone

As per previous posts not had any joy with support from GP so have been taking advice here and am seeing an endo privately to hopefully get a diagnosis of Hashimoto's. Have just done blood tests prior to apt and got the results back. My levels have been the best I've ever seen (first blood test was in 2017), except for TSH, which I'm super pleased about but on the days I feel bad, I feel pretty rubbish. Can anyone shed some light as it doesn't make sense to me as to why I feel worse. FT3 is the important one I thought for symptoms but my FT3 is the highest it's ever been!

Or is it the high ferritin that's actually causing the symptoms? Haven't been sleeping brilliantly so could also be that.

(Have been taking b vits, selenium, zinc, vit d loading dose, magnesium for a few months (stopped b complex 7 days before test). Gluten and dairy free for a couple of weeks now). Thanks in advance!

Edit: not currently on any medication

CRP 1.29 (<5)

Ferritin 353 (13-150)

Folate 18 (>3.89)

Vit B12 150 (>37.5)

Vit D 103 (50-175)

TSH 3.59 (0.27-4.2)

FT3 6.05 (3.1-6.8)

FT4 14.6 (12-22)

TgAB 219 (<115)

TPOAB <9 (<34)

I very much doubt you'll get a diagnosis of Hashi's with that low TPOab. The NHS does not recognise TgAB as being indicative of Hashi's without high TPOab.

Your FT3 may be high-ish but the question is: how long has it been like that? Long enough to get rid of symptoms? With Hashi's, levels tend to jump around as hormone leeches from damaged thyroid cells. Look at your TSH. That is high - although not by NHS standards - so your FT3 probably hasn't been that high for very long.

I don't know if high ferritin causes symptoms. But, you haven't been gluten or dairy-free for long enough for it have had much effect yet. So, patience is still needed, I'm afraid.

Thank you, that helps. Yes ft3 has been that for weeks if not days. Patience is a virtue!

You're welcome.

You perhaps need 25mcg dose increase in Levothyroxine

TSH still too high

FT4 too low

FT4 only 26% through range

FT3 a whopping 79% through range

FT3 is impressive...but may be result of Hashimoto's flare

Be interesting to see if endocrinologist will acknowledge Hashimoto's on only high TG antibodies (doubtful)

Ferritin high

Have you had full iron panel testing to see if iron is also high?

I’m not actually on any medication! I was hoping endo would be prescribe me some when I see him on Saturday but on these results I’m not so sure. As mentioned elsewhere I’m sort of looking to conceive so tsh should be under 2.5... the lat iron panel I had was 2018 and iron was the top end of the ‘normal’ range. Thanks that helps

Sorry...I should have read your previous posts

Well TSH should be under 2.5 before TTC

[Arlie123 in reply to SlowDragon]

I should have made it clearer!
