My TSH recently was 2.4... I've read some places that that can be classed as hypo? Maybe that could be linked with b12 / folate issues

Thyroid issues are usually autoimmune based so in that sense they’re linked to PA. If you have one autoimmune illness it seems you’re more likely to have another. For example, I have thyroid issues, vitiligo and PA, all autoimmune illnesses.

You might be better asking about a TSH level of 2.4 on the thyroid forum but in my inexpert non-medical opinion that on its own doesn’t mean you have thyroid issues. In my GP surgery a level above 5 would flag a problem possibly needing treatment and I understand that in other areas treatment wouldn’t be considered unless the level is above 10.

If you have a concern about your thyroid you would really need a full thyroid panel carried out as TSH on its own isn’t really enough to diagnose. I’m not sure of the detail but this would include a test for 2 or 3 different types of thyroid antibodies and checking your levels of Free T4 and Reverse T3.

I have been told by one of the many people who go back and forth between this forum and thyroid one that ideally TSH should be around 1, and that ideal FT4 is 3/4 of range.

So if range is 12-22: span of range is 10, x 0.75 = 7.5 , + 12 (btm of range) = ideal of 19.5.

Nearest I've come to that is 1.53 and 14.9 - just not at the same time, haha !

My TSH has been as high as 3.39 and no-one seemed concerned about it.

To work out what is happening, check previous figures and see what way these are heading. This is only part of the picture; you also need to know what FT3 is doing.

I got a private postal blood test for full-panel thyroid results :

TSH, FT4, T4, FT3, and thyroid antibodies: anti-TPO, anti-TG .

(NHS in UK generally only gives FT4 and TSH results)

I don't have a thyroid problem but have 2 sisters with Grave's disease, so like to have it checked. Deficiencies can cause thyroid to struggle long-term and there is a link between autoimmune diseases: if you have PA, you are more likely to have others too. If you are worried and feel you need more info, there are plenty of knowledgeable people on Thyroid UK forum who can help.

Cherylclaire - please note that comments on TUK concerning need for TSH to be around 1.0 relate to levels once someone has started treatment with levothyroxine.

Please also note other comments in my response below

This post is off topic - it would be better to post on TUK forum if you haven't done already

healthunlocked.com/thyroiduk.

TSH of 2.4 is well within the normal range for thyroid function - meaning it is unlikely that you have a thyroid problem (assuming you are not undergoing treatment)

TSH however, suffers from some of the same limitations as serum B12 and TSH is really a test that forms part of a suite identifying where are the most likely places to follow up on and the range post treatment genuinely does seem to be very different from that before treatment - and most patients who are being treated seem to need to maintain levels around 1.0.

TSH is also an indirect measure of thyroid function.

As it is off topic for this forum I am going to close it to further responses.
