Help Interpret my Test Results

I did these tests a while ago with the NHS, but my GP said that I am absolutely fine. I am still feeling poorly all these years. Can someone see anything wrong in the results or do I need to do more tests, is so, which ones?

Your help would be sincerely appreciated.

Are you still on NDT? How much are you currently taking

Did you take past dose 12 hours before blood tests

Your FT3 is very low at 3.5 (3.25-6.1)

TSH is within range, which is unusual on NDT as it's usually suppressed on NDT

Presumably you supplement vitamin D?

If so how much

Are you also taking any magnesium? Magnesium result is on low side. Many thyroid patients have low magnesium and benefit from supplementing

Importance of magnesium


Thank you for your analysis SlowDragon.

When I did the test, I was on one grain of Nature-throid per day, but I have not taken any NDT for over a year now because I did not feel any improvement then. I skipped the dose on the day of the test.

I was taking 3000IU of Vit D for 2 months but not any more as it did not make any difference.

The only supplement that really worked for me was Raw Adrenal by Natural Sources

, I felt very energetic and outgoing, but it only worked for a week and I stopped feeling the effect.


So this result is over a year old? And was when on one grain NDT. FT3 was low

No antibodies tested either

For full Thyroid evaluation you need TSH, FT4, FT3 plus TPO and TG thyroid antibodies and also very important to test vitamin D, folate, ferritin and B12

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have money off offers.

All thyroid tests should ideally be done as early as possible in morning and fasting.


It's impossible to view these results, even enlarging the text on my laptop, sorry. Could you possibly type the results for vitamins, thyroid and antibodies?


Did you click on the link in the post?

That is to a much higher resolution image. :-)

I would have clicked on the link if there had been an explanation of what it was for.


Ok, thanks, just followed the link.


I've scanned your results, a lot to view. I can't find any results for thyroid antibodies, the initial test stated that they needed to be redone. Do you now know whether you have thyroid antibodies or not?

You could ask your doctor if your calcium results are a bit low although in range. If so, then check you are eating enough calcium rich foods and that your vitamin D is sufficient over the winter. As SlowDragon has said, magnesium is on the low side so if you supplement it could help to untilize calcium from your diet as they work together.


Your problem atcthe time wastou weren't on a high enough dose andcthe alternative you tried worked for a short time then stopped. That may be because your body needed it so you felt better for it but then if it's not enough then you go back to feeling not so good again.

Nothing works quickly in the Thyroid world, we can't speed it up so lots of patience is needed. Ones who have tried find that often they have had to go back to the beginning and start again. We have to start low to get our bodies used to it and that is more important taking any form of T3. So it can take up to 6 months to find the dose which is right for you as we are slowed down by the retesting every 6 weeks. The 6 weeks is very important as it takes that time to get each new dose fully into our body. As I said it doesn't work to cut corners!


Just have put above but Thyroid Uk who run this site have loads of info on there as well. Shout out if anything you don't understand.
