Normal TSH, low T4 and T3

Ribenablackcurrant profile image

Hi,

My TSH is relatively normal if slightly low. I had these results in May this year.

TSH: 1.17

T4 12.2 (I'm on Levothyroxine)

T3 2.48

Has anyone else has results like this? My doctor's don't seem to have any suggestions!

Thanks in advance :)

Well to comment we would need to know how much levo you are currently on and the ranges for those results. Otherwise we would just be guessing.

I am taking 25/50 mcg on alternating days of Levothyroxine

What about the ranges for your results?

Looks like subnormal TSH secretion or even secondary hypothyroidism. We need the reference intervals (numbers in brackets) for TSH, fT3 and fT4 to comment.

How did everyone here get their FT4 & FT3 tested? I have had private thyroid hormone tests in the past and they didn't offer to do them either

That's surprising, they are usually done. You can find details here thyroiduk.org/getting-a-dia... . I haven't used these tests but I suggest using the Monitor my Health one because it is probably the cheapest and because it is an NHS lab doctors will find it difficult to reject the results. Antibodies are not tested but I feel that in most cases antibody assays are not much use.

Not what you're looking for?
