Help interpreting Medichecks Advanced Thyroid blood test

[The-Wasp]

Hi there! Would any of you be willing to help me interpret these results? I have been on a strict gluten free, dairy free, sugar free, soy free and low iodine diet for a couple of months and have felt A TON better. These results bear this out. I'm on 100 mcg of Levothyroxine and 5 mcg of Cytomel. The only values that seem at all close to out of range seems to Free T3. According to Isabella Wentz (the Thyroid Pharmacist) I think it should ideally be between 5 and 7 pmol. My symptoms bear this out as I feel great in the morning and then symptoms start to sneak back in towards the afternoon. I have a few appointments with some private NDT's and an endo as the NHS is not allowed to prescribe T3. I'm from Canada and have been on this dose for 25 years. I wonder if I'd feel better if I found someone willing to prescribe another dose of 5 mcg midday and perhaps afternoon for a total of 15 mcg split into 3 doses. I'm new to all this so may be way off base. Is a private endo or NDT likely to prescribe T3 based on these results?

THYROGLOBULIN ANTIBODIES 17.1 kIU/L 0 - 115 R

THYROID PEROXIDASE ANTIBODIES 11.9 kIU/L 0 - 34

yes …you need to add a 2nd 5mcg dose T3 approx 10 hours after the first dose

Wait perhaps 6 weeks and retest ……before considering adding 3rd dose

Email Thyroid U.K. for list of thyroid specialist endocrinologists and doctors who will prescribe T3

Roughly where in U.K. are you

Some on list are doing consultations on zoom

Private prescription enables access to Thybon Henning 20mcg tablets via specialist U.K. pharmacies

Cutting 20mcg tablet into 1/4 to get 5mcg dose

According to Isabella Wentz (the Thyroid Pharmacist) I think it should ideally be between 5 and 7 pmol.

Your FT3 of 3.2 (3.1-6.8) is certainly very low but you can only use Isabella Wentz's suggestion if she is referring to the same reference range as that which came with your test. Obviously she is using a different range because a level of 7 would be over range with the test you've done. You can only use the range that comes with your own test, you can't mix and match a result from one lab's test with a range from another lab.

With your range a level between 5.7-6.1 would give a percentage between 70-81% which is possibly a good place to aim for.
