Hashimotos/ subclinical?

[Aesm]

I would be grateful for a little advice following my recent blood tests so that I’m prepared when I return to see the endocrinologist.

TSH 0.35 (0.3-3.6)

FT3 2.0 (2.2 - 4.2)

FT4 0.83 (0.8 -1.7)

I am currently on 100mcg levothyroxine (triosint). When I last saw the endocrinologist she suggest that I may need to have my medication lowered as my TSH was suppressed at 0.03, (FT3 2.21 and FT4 1.06). She didn’t rush to do this without a further blood test , but she did refer to me having sublinical hypothyroidism, (Hashimoto's TPO 88.74 (1.0 -16 ) , is this significant? I am feeling much better on this dose, although still not quite right, and clearly my levels are still pretty low. I live in Italy (where the health care is actually very good I think) and need to go prepared to help with language etc.

Thank you.

T3 is the active thyroid hormone which controls nearly every cell in the body. The free T3 is therefore the most important test result. Your Free T3 is near the bottom of the normal range and needs to be higher.

TSH is not a thyroid hormone. It is produced by the pituitary and signals to the thyroid gland to make more hormones.

When the doctor has the free T3 result it should be the main factor in determining treatment, not TSH.
