Just got this months bloods back below. Does thyroid look close to optimal now? Have increased from 50 to 75 to 100 mcg Levo over past 6 months or so. I am trying for 2nd baby and my progesterone blood test showed i didnt ovulate 
I was sort of hoping my thyroid was cause but I think my results are quite good.
Thyroid function test
Serum TSH level 0.32 mu/L [0.3 - 5.0]
Serum free T4 level 10.2 pmol/L [7.9 - 16.0]
No, doesn't look optimal and no free T3. FT4 is only 28.4% through range and for mot people needs to be at least 50% (around 12) - many need it higher in order to make enough FT3.
Oh ok thanks for reply, so you think increase levo by another 25mcg? The tsh is already very low though, do you think increase would be ok?
Just testing TSH and Ft4 is completely inadequate
Do you always get same brand of levothyroxine
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
Do you have Hashimoto’s?
Ask GP to test vitamin levels
You may need to get full Thyroid testing privately as NHS refuses to test TG antibodies if TPO antibodies are negative
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, best not mentioned to GP or phlebotomist)
Is this how you do your tests?
Private tests are available as NHS currently rarely tests Ft3 or thyroid antibodies or all relevant vitamins

Thanks, yes am hash/hypo, have had vits tested and discussed on here, all ok apart from vit b and ferritin which am now supplementing, ft3 was low.
Had bloods drawn first thing before food, and took levo 24hrs beforehand.
Do you think i should increase 25mcg levo to 125mcg? Not sure i would want tsh going any lower though?
TSH is irrelevant. Most important results are Ft3 followed by Ft4
Ferritin needs much improvement
Suggest you reread all this previous post
Looking at previous post
Clearly ferritin is a problem
GP must retest full iron panel Every three months when supplementing Ferrous fumerate
As you have Hashimoto’s are you on strictly gluten free diet or tried it
No not strictly gf diet. I was hoping if medicated properly i wouldnt have to :/
Sorry doesn’t work that way.....being strictly gluten free often helps improve symptoms and may help improve thyroid and vitamin levels
Improving nutrients improves conversion

Also ....guidelines by weight might help push for dose increase.....depending on how much you weigh
Even if we don’t start on full replacement dose, most people need to increase dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until on full replacement dose
NICE guidelines on full replacement dose
nice.org.uk/guidance/ng145/...
1.3.6
Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.
BMJ also clear on dose required
Post re how to push for dose increase in levothyroxine
healthunlocked.com/thyroidu....
Thanks. Judging by the weight I should on 75mcg more at 175mcg!
So you likely need to continue slowly increasing levothyroxine and extremely important to improve vitamin levels at same time
Strictly gluten free diet frequently helps or is absolutely essential
Endo sent below response. I had increased to 125mcg levo as had spare but endo wants to keep me at 100. Think have scuppered chance of increase dose to maintain good results t4 results which is over 60% through range :/
"Thank you for your message today, sent as Advice Conversation. I note the query about thyroid replacement therapy. I have read the email exchange you included with the message and I have seen the blood test results. The email exchange includes advice to aim for serum TSH in the lower part of the reference range. This is in line with standard practice and our local practice also. The last blood test result included TSH 0.08mU/L (which is below the reference range). I agree that on the basis of the available information, there is no indication to increase the dose of Levothyroxine."
