What would you say about this thyroid reading? ... - Thyroid UK
What would you say about this thyroid reading? TSH 0.11. The two underneath are FreeT4 and Total T3?
Nor should he - unless it's an increase in dose. There's plenty of room for an increase, your FT4 isn't even mid-range. Don't allow him to reduce your dose simply on the basis of a low TSH. That is the least important number.
The most important is the FT3. But, he hasn't even tested that. I'm afraid the TT3 doesn't give us any useful information.
Just testing TSH and Ft4 is completely inadequate
Ft4 is low at only 41% through range

For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12
Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies
Ask GP to test vitamin levels
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
If/when also on T3, make sure to take last third or quarter of daily dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test
Is this how you do your tests?
