All advice gratefully received.

Results show FT4 is still on low side. You really need FT3 tested.

Doubt your GP will agree to dose increase. They will just look at low TSH

Have you retested vitamin D? And how much are you supplementing

Are you also taking a good vitamin B complex with folate in (not folic acid) to improve folate

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 3-5 days before any blood tests, as biotin can falsely affect test results

Ferritin was very high previously. Did that get investigated

Did you change to strictly gluten free diet?

I may have made a mistake on the last test, as I took B12, liquid up to the day before.

yes glutten free, Dr. said ferritin not to worry about, as other tests do not show anything untoward. not sure what was tested though!

It's only vitamin B complex that needs to be stopped 3-5 days before, because biotin in it just might upset the test.


You haven't stated what the "Frees T ? range" is (i.e.3 or 4). This is a copy from above:-

TSH 0.68 (.34-5.6) free t 11.40 (

Your doctor will be happy with the TSH and may not increase your dose but both Frees should be in the upper part of the range.

If the doctor only take account of the TSH alone and may think you don't need an increase but the fact that both FT4 and FT3 are low in range you do need an increase in dose. I read the other day (from a member) that FT3 should be in the top third.

You need an increase in levo to increase both frees towards the upper part of the range. You might feel better if some T3 is added to T4 but you might have to source this yourself. Research has shown that many prefer a T4/T3 combination but most doctors are not prescribing T3.
