TSH 1.6 mlU/L 0.27-4.20mlU/L
T4 23.6 pmol/L 12.00-22.00 pmol/L
Free T3 3.07 pmol/L 3.10-6.80pmol/L
So FT4 is over range and FT3 under range.
Your conversion is very poor. Good conversion takes place when FT4: FT3 ratio is 4:1 or less. Yours is 7.68 : 1
As I said increasing Levo won't help. You need Levo reduced by 25mcg initially and the addition of T3.
It is very difficult to get T3 prescribed at the moment but I would be pushing your GP for a referral to an endo to try and get it. Email email@example.com for the list of thyroid friendly endos then ask on the forum for feedback on any in your area.
As T3 is the active hormone that every cell in our bodies need, it is very important that your below range FT3 is addressed.
[Supplementing with selenium can help conversion of T4 to T3, and optimal levels of vitamins and minerals will also, particularly ferritin.]
Folate should be at least half way through the range, 11+ with your range, so yours is a bit low. Folate rich foods (leafy greens) can help, and a B Complex containing methylfolate folate would be a good idea.
B12 is fine.
Ferritin 47ug/L 15-445ug/L
This is dreadfully low and should be half way through it's range. You probably won't be prescribed by your GP as you are in range, so you will have to buy your own iron supplement such as Ferrous Fumerate (from Amazon) or if that causes problems then iron bisglycinate is more gentle (eg Solgar Gentle Iron). Take each tablet with 1000mg Vit C to aid absorption and help prevent constipation. Take iron four hours away from thyroid meds and two hours away from any other medication and supplements as it affects their absorption.
Creatinine is slightly over range. It is a kidney test, your GP might want to keep an eye on it.
The others are all in range.
