Results to some bloods

[Lanvere]

Can someone just have a quick look at these for me I'm still trying to get my head round it all ..

Tsh 3.19 (0.35 - 5.00)

Free T4 12.3 (9.00-22.00)

B12 236 (200 - 800)

TPO Antibodies- positive

I know the B12 is too low and will need supplements

And although within range the other results are not right but I'm not sure why

[Caesard]

I wouldn't comment on that without a clinical context. Are you on a substitution treatment?

If it would have been my tests, in my condition, I would have considered TSH a little too high and FT4 borderline low (in my country normal range for FT4 is considered 12-22 pmol/L)

B12 seems also low, my reference interval is 191 - 663 pg/mL

It's my oldest son and he is not on any treatment

[Caesard in reply to Lanvere]

Do you happen to have older test results from history? If yes, are they significantly different?

Is there any reason to complain, your son has any kind of symptoms associated with a potential thyroid issue? Because, after all, the results seem within standard limits, in absence of history (including thyroid disease in the family) and symptoms those are not bad results and may be the normal set-up of his body.

There is significant family history me, my mum, my grandmother, aunts, uncles, cousins, my sister and my youngest son all have hasimotos hypothyroid ... this son is gaining weight despite dieting and is tired all the time

His TSH is too high, his thyroid is struggling. But doctors in the uk like to leave it until the TSH hits 10 before they will diagnose. Or, they might if the FT4 is below range. Your son's is low but not quite below range.

But, he does have Hashi's, so the chances are that his TSH will eventually reach 10. Things are going to get worse, I'm afraid, not better, no matter how deep your doctor buries his head in the sand.

Yes, the B12 should be at least 500. But has he not had his folate tested, too? Because the to work together. All the Bs work together, so, if he supplements B12 (sublingual methylcobalamin) he should also take a B complex.

He should also have his vit d and ferritin tested, because these are likely to be low, too.
