Hi there Some advice please I’ve just had results back which showed my TSH level was 0.01 Range 0.35-4.34 My GP is concerned as it has gone down Omer the last year I’m currently taking 1 3/4 NDT plus 50 Levo she wants me to lower the Levo to 25
Other levels are : T3 3.70 ((3.63-5.70)
T4 10.40 (9.01-19.05)
Any advice I would be grateful Many thanks

Is your NDT prescribed? If so then whoever prescribes it should know how to read test results when taking it. Taking NDT lowers, even suppresses TSH, it's just what it does. We don't need to worry about that, the important results are FT4 and even more important FT3.
If you reduce your Levo your TSH probably wont increase because you'll still be taking NDT.
Your FT4 is already very low in range and will reduce even more if Levo dose is reduced.
Your FT3 is also extremely low in range for someone taking NDT.
If anything your dose of NDT needs increasing and Levo dose kept the same.
How do you feel on these doses?
Out of interest, when did you take your last doses before that test? Last dose of Levo should be 24 hours before test. For NDT it should be split into 2 or 3 doses the day before and last part of dose should be taken 8-12 hours before the test. Any longer than these times and you get false low FT4/FT3 results.
Hi I get my NDT from Thialand so it’s not prescribed. I think I probably had the blood test too late in the day. I probably took my last meds 18 hours before!!!
Thank you for replying. I don’t know if I feel ok. Some days I do some I don’t. Still having night sweats.
Hi pennyannie. Thank you for reply. Yes I have heard that TSH is suppressed but that just seemed very low. Think I left it too long between last dose and blood test too. But last blood test it was very low too which was why she wanted me to start taking the Levo.
Thanks for your reply. So I still need to get my T3 level up. With the NDT are all the bottles providing exactly the same ratio of T3and T4 do you know?
You say you buy from Thailand and as I understand it Thyroid S is the only one now available and each grain contains a measured amount of both T3 and T4 that being :- 9 mcg T3 + 38 mcg T4 :
There are other brands from the States the most well known one being Armour and that too contains 9 T3 and 38 mcg T4 - I believe some other brands have a slightly different measure of T3 and T4 - but this should be stated on the bottle and PIL :
Tell GP to look at your thyroid hormones which are both low in range not high. GP shouldn’t use TSH to dose. Low TSH with ‘normal’ thyroid levels is not a risk for Osteoporosis or Atrial Fibrillation.
I was looking at posts about low TSH because I suffer with nightly night sweats and have very low TSH. Mind if I ask if you have found a cause for yours and did you manage to remedy the problem?
Hi. Unfortunately no I haven’t found the answer to the night sweats. Just pulling the sheet on and off most of the night. I have just started taking selenium which is supposed to be helpful for thyroid. I wish I had the answer 😞
