Anti thyroid peroxidase 339ug/L how to interpret this

[anntroberts]

I had a partial thyroidectomy in 2006 and thyroid results have been fine ( with a 72ug/L previously. The 339 is well over the 150ug/L, can I assume I have Hashimoto's?

The GP contacted me about this, and he felt my other results did not warrant any medication.

TSH is 2.72 mlU/L, Range 0.27 - 4.20

T4 Total is 114.0n mol/L, Range 66 -181

Free T4 15.1 pmol/L. Range 2.0 - 22.0

Free T3 is 4.25 pmol/L. Range 3.1 - 8.8

I am feeling low, sluggish, consitipated, some hair loss and I wonder if I would benefit form going back to the GP and look to go on levothyroxine.

Any advice/ insight welcome Thanks

Yes high TPO confirms hashimoto's

Essential to test vitamin D, folate ferritin and B12 too

What vitamin supplements are you currently taking

Was this test done as early as possible in morning before eating or drinking any thing apart from water

I realise that I gave the wrong TPO figure, When I went to my GP the TPO came back at 388.3 IU/ml Range 0-100. I then arranged a further test privately as requested by my private nutritionist.

Results were

Anti-Thyroidperoxidase abs 80 klU/L. Range >34

AntipThyroidglobuln Abs. 272 kIU/L Range >115

Ferritin. 339.0 ug/L. Range 13 -159

B12 -active 108 pmol/L Range > 37. I supplement this

Serum Folate. 21.6. nmol/L Range 8.83 - 60.8

Vitamin D ( 25OH). 157.0 mol/L I supplement this and report feedback suggested I cut back on this

Yes test was done 8am after overnight fasting

Any further insight welcome :). thank you

You can't be certain but it's probable that the high TPO reflect some degree of thyroiditis and it may damage your thyroid.

More to the point you had a partial thyroidectomy and although your hormone levels aren't too bad (assuming typical reference intervals) it makes sense to treat your symptoms with a trial of levothyroxine. A three to six month trial is reasonable, your fT3 is a little low and you only have half a thyroid.

Thank you. I have an appointment with the GP next week and I was not sure how receptive they would be to me asking for medication to see if I can improve how I am feeling.
