I put up my first post 9 days ago with results from my recent test but I did not have the ranges. According to the GP I was over treated although I had no symptoms to justify. My Levothyroxine was reduced fro 100mcg to 75mcg. I now have the lab print out which gives the following:
TSH - 0.03 (0.35 - 5.00) mu/f
FT4 - 24.2 (9.0 - 21) pmol/l
FT3 - 4.4 (3.0 - 6.0) pmol/l
I hope this helps to get some advice based on the above. To be tested again in 2 months.
Thanks
All thyroid tests should be done as early as possible in morning and fasting and don't take Levo in the 24 hours prior to test, delay and take straight after. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)
Is this how you did the test?
Your results show you are probably a poor converter
TSH very low
FT4 slightly over range
FT3 too low
On reduced dose FT3 will drop futher
You need thyroid antibodies tested, plus vitamin D, folate, ferritin and B12
What supplements do you currently take
Selenium supplements can help improve conversion of FT4 to FT3
This test was done at 12.30. I take several supplements
CoQ10
Vit D3 50ug
Vit C 500mg
Ginkgo Bilboba 30mg
Garlic 3mg
Omega 3 fish oil
Korean Ginseng 500mg
Brewers Yeast 500mg
Magnesium Citrate 100mg
Calcium 500mg
Glucosamine and Chondroitin
Zinc 15mg
Multivitamin/mineral
Just started Vit B12 100ug and Vit K2 90ug
I also have type 2 diabetes, diet controlled
Should read Ginseng Biloba!
I will ensure that my next test is in the early morning and will not take Levo 24 hours before. I will also ask for Vit D, Vit B12 and ferritin and will get selenium supplement.
Multivitamins generally have iodine in. Not a good idea if you have Hashimoto's
drknews.com/iodine-and-hash...
Stop any supplements that contain biotin 3-5 days before any blood test
You need folate tested too
Thank you. I had been reading up on Biotin, which is contained in Brewer’s Yeast and the multi vitamins, so will definitely stop both three days before testing. Thanks!
Well, you were over-medicated on levo. Trouble was, you can't convert it very well and your FT3 is very low. What you need is some T3 added to your reduced dose of levo. But, I don't suppose your doctor will agree - or even understand why. Maybe you should consider buying your own?
I am considering buying it but wonder if I should wait for the next results and discuss with my GP? It is so strange that I had not symptoms of being over treated but still have symptoms of hypothyroid eg constipation, very dry skin and great difficulty losing weight. I have been on a low carb diet for two months and in the last month have lost no weight. I am so tired, feel that I am slowing down. I did have a GP who prescribed based on symptoms but he retired and now they just do not care.
Thank you for advising me!
It's not strange at all. Your FT3 is low, and that's what causes symptoms - not the TSH or the FT4. You couldn't possibly have symptoms of being over-treated with such a low FT3.
It could be your low-carb diet the problem. You need carbs to convert. If you don't convert, your FT3 drops, you become more hypo and put on more weight. There's no mystery.
Thank you again. My dilemma is that low carb is recommended for lowering blood glucose for type 2 diabetes. However I will change my diet from low carb because my thyroid symptoms are the outstanding problem here as my diabetic control is good. How would I know the correct dosage of T3 to take? I wish I had joined this forum a long time ago because there is so much that I have learned already in just a couple of posts.
You cannot know which is the right dose of T3 to take. You just do as you would with any other hormone : start low and increase slowly.
Start with a 1/4 tablet of T3, reducing your levo by 25 mcg, and increase by 1/4 tablet every 2 weeks until you get to one whole tablet, then hold for six weeks and retest. 
Essential to test vitamin levels first before considering introducing T3
Plus you need to know if you have Hashimoto's. If vitamins are low especially, gluten intolerance is often hidden issue
I am going to request Vit D, Vit B12, folate, ferritin and antibodies as well as full thyroid test at my next due date of 6 Oct. That is the date I have been given to test, 2 months after the reduction from 100mcg to 75mcg. It cannot come fast enough because I am already feeling worse than I did.
Personally I would test privately
Needs to be 6-8 weeks after any dose change.
8-10 weeks probably better after dose reduction
NHS often refuses to test FT3 or antibodies
Apparently the lab used by my surgery now tests for FT3. The print out has a note that says (Note new FT3 in use from 01/02/18). I live in Scotland. My FT3 on this print out was 4.4 (3.0 - 6.0).
So on reduced dose it may drop lower (doesn't always)
Most people need FT3 at least over 5 to feel well
Both TPO and TG Antibodies need testing, if never been done
thyroiduk.org.uk/tuk/about_...
I am going to request for antibodies to be tested. Hopefully the GP will agree! It will be interesting to see my other results at next test.
You will need both TPO and TG antibodies tested.
If TSH is within range lab often refuses to test either antibodies even if GP has requested.
If TPO are negative then Lab usually refuses to test TG antibodies
I will get a private test if either the GP or lab refuse. Thanks for that advice. It is so bad that there has to be such a fight to make sure that your health needs are addressed but I mean to persevere!
Did you have those tests done ? B12 - Folate - Ferritin - VitD ?
He only agreed to test Ferritin, which was said to be normal at 50!
Have you considered private testing through Thyroid UK - Like 1,000's on this forum do ... ?
I am a pensioner and it is really too costly from me, but thanks for replying.
