New Results: Please Help Interpret!

Hi everyone,

I just got my new results back and would appreciate any advice before seeing my endo tomorrow afternoon. I have been on 125mg of Levothyroxine. Endo has switched me to taking levo at night, other then that there has been no change and I have been on this dose already with my March results. Endo wanted to see if taking the dose at night would make me feel better, and if not a) check nothing else is going on and b) start looking at options for addition T3 or taking NDT instead in our next session.

NEWEST RESULTS:

TSH level 0.43 mU/L [0.3 - 4.2]

free T4 level 15.3 pmol/L [9.0 - 23.0]

free triiodothyronine (T3) level 3.7 pmol/L [2.4 - 6.0]

Cortisol Level: Serum cortisol level 556 nmol/L [160.0 - 550.0]

Serum ferritin level 149 ug/L [10.0 - 120.0]

Not sure this is relevant BUT: They tested some general other blood tests, everything was normal except these two:

Serum bilirubin level 22 umol/L [0.0 - 21.0]

Lymphocyte count 3.7 10*9/L [1.1 - 3.6]

*I do have a current bulging disc in my lower back, so not sure if this is why this could be raised?

**Note: annoyingly they wouldn't test my vitamins again on the NHS as they said the levels were all normal last time! (Trust me, I tried!!) Annoying as I wanted to re-test folate after some of you said it wasn't good enough :(

LAST RESULTS: *this was done with medichecks, my newest results above are on the NHS

TSH: 0.57 mIU/L (Range: 0.27 - 4.2)

Free T3: 4.9 pmol/L (Range: 3.1 - 6.8)

Free Thyroxine (T4): 19.8 pmol/l (Range: 12 - 22)

PREVIOUS RESULTS FROM 1st of FEBRUARY: (When i was on 100mg)

TSH: 1.73 mIU/L (Range: 0.27 - 4.2)

Free T3: 4.2 pmol/L (Range: 3.1 - 6.8)

Free thyroxine: 18.2 pmol/l (Range: 12 - 22)

Hi thyroidqueen12,

From your prior posts it appears you're on the cusp of getting off straight levothyroxine and maybe trying NDT. I'd try asking for that if possible. The second choice, and probably the endocrinologist's choice, would be adding some liothyronine (T3) with your levothyroxine. That might help, unless you're genetically predisposed to not converting the levothyroxine well. Adding T3 mightn't help at all, but endocrinologists can be stubborn.

The elevated lymphocytes and bilirubin could be something that more complete blood cell examination would shed light on. A complete iron panel, a reticulocyte index and a peripheral blood smear might add further insight. You do need to know ferritin, iron, total iron binding capacity, and whether you produce a healthy complement of red cells. All this is necessary to carry oxygen to your brain and to fuel cellular energy.

I'd press for more tests to try to get to the bottom of what's happening with oxygen-carrying capacity. And change to NDT if you can.

Good luck

I'm curious!

That ( adding some T3) might help, unless you're genetically predisposed to not converting the levothyroxine well.

Please can you explain what you mean by this

You appear to be suggesting that the addition of T3 will not help if the Dio2 snp exists

Am I understanding your comment correctly?

If one has the Dio2 polymorphism then conversion is impaired

Heterozygous...not a lot

Homozygous ...more so

In either case the addition of T3 can help.

You appear to be suggesting the converse.

If T3 is low, health suffers...

So once levo and essential nutrients are optimised and symptoms still exist replacement T3 is required to provide the body with a T3 level adequate to maintain good health.

thyroidqueen12 has low FT3 levels

RockyPath in reply to DippyDame

Hi DippyDame,

We meet again!

Peripheral tissue (all else outside the pituitary) rely on DIO1 enzymatic activity. A DIO1 polymorphism resulting in poor conversion will starve the tissues. Meanwhile the pituitary is happily steaming along on its well-functioning DIO2 enzymes.

In the pituitary, 80-90% of T4 is converted to T3 via DIO2. Only about 30-50% of T4 in the peripheral tissue is converted to active T3, due to the inefficiency of DIO1. The production of reverse T3 is poorly conceptualized, but some snps are known to boost conversion of T4 to reverse T3. When levels of rT3 becomes sufficiently high, there's nothing the liothyronine can do to overcome it, for the rT3 is bound to the sites that one would hope the T3 would glom onto.

D2 also has an opposite response from that of D1 to physiologic and emotional stress, depression, inflammation, and systemic illness. D2 is stimulated and there's increased activity in response to such conditions. DIO2 (intra-pituitary) T4 to T3 conversion goes up. But the rest of body suffers from diminished levels of active T3. This causes the TSH to remain normal, despite the presence of significant cellular hypothyroidism in the rest of the body.

Thyroidqueen might do fine on levothyroxine and some T3.

Or not.

The "or not" part can be drawn out, extremely trying, and fraught with physical exhaustion and despair.

On the other hand, the weeks I lay languishing on the bed unable to do anything were well spent going through my raw genetic data and identifying all of the DIO1 and DIO2 enzymes and their genetic markers and then researching clinical articles to find which ones were know sources of trouble when treating with levothyroxine. And which ones contribute to osteoarthritis.

I hope this explains some of where I'm coming from with my remark.

As ever, appreciative of everyone's keen interest to helping each other.

"for the rT3 is bound to the sites that one would hope the T3 would glom onto."

Is it ? ...... i thought i had understood that ReverseT3 can't fit onto the T3 receptors in the cell nucleus....... have i misunderstood which receptors/sites you mean .. or have i missed bit in my logic ?

RockyPath profile image
RockyPath in reply to tattybogle

Yes, I confess I haven’t actually been inside my cells to watch what’s happening. I’ve only this, from numerous laboratory blood tests for rT3, and correlation with profound physical exhaustion when its proportion to FT3/4 was high:

Reverse T3 does something awful, when there’s too much of it. It can be a monster.

DippyDame in reply to RockyPath

Thank you for responding RockyPath

A complex explanation...

And raising the controversial subject of rT3

I will be interested in your response to tattybogle I understand rT3 does not block T3!

In any case, I doubt that thyroidqueen12 has a high enough level of T4 to produce rT3

I quote from Tania Smith's work -

Neither Reverse T2 nor RT3 have enough affinity to the thyroid hormone receptors in the nucleus to bind with it.

thyroidpatients.ca/2019/11/...

An eminent scientist has said of Dr Smith...

She certainly shows logic and reasoning to the best extent.

I'm neither a thyroid scientistist nor a medic so, like you, have had to attempt to learn from the learned.

In my case, in order to recover from RTH/ cellular hypothyroidism.

I have recovered from very poor health thanks to support from experienced and knowledgeable members here.

I cannot claim to be an expert in this field so appreciate the greater knowledge of others.

Like tattybogle -whose knowledge is invaluable on this forum - I wonder if I too have missed something here

for the rT3 is bound to the sites that one would hope the T3 would glom onto."

thyroidqueen12 asked members of the forum for their experiences/opinions on the various treatment options presented to her by her endo.

I agree with her decision to choose T3 over NDT....just my opinion!

It really is a rediculous situation that as lay people we thyroid patients have to find the solutions to resolve our (often desperately) ill health because the experts failed.

I hope, following you challenging time, that you are now keeping well.

Like you I hugely appreciate the amazing help and support offered here

Take care.

Hi RockyPath,

Thanks for your reply. All of my other Liver function tests were normal. I also had a full blood count report, where everything was also normal apart from the Lymphocyte count.

Re-Thyroid treatment: I am not leaning towards NDT over adding T3. My last post was wondering what others found worked best for them. My endo has said that either T3 or NDT are my next options if I'm still not feeling better & he doesn't find anything else going on which might cause this. Although now that there is a raised cortisol results (on a day where I felt the best in a while), I assume he will try something to treat this first. We'll see this afternoon...

thyroidqueen12 in reply to thyroidqueen12

Oh, also: I've never had one of those gene tests done as my endo said he doesn't think they work well. If he will consider giving me T3 with just showing poor conversion, then I'm fine with that.

High cortisol should reduce once T3 is added

Adrenals try to compensate for lack of thyroid hormones

Was latest test done early morning, ideally before 9am and last dose levothyroxine 24 hours before test

If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test

If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal

FT4: 15.3 pmol/l (Range 9 - 23) 45.00%

FT3: 3.7 pmol/l (Range 2.4 - 6) 36.11%

Hi SlowDragon,

Yes early morning before 9am. I posted on here in regards to my 24hr issue: i was not told about procedure if taking levo at night, as my endo said to just take it normally since it's far enough away from testing. So i took my normal dose at night, and got the blood taken at 8.45am.

Folate - Serum: 3.6 ug/L (Range: > 2.9)

Vitamin B12 - Active: 76 pmol/L (Range: 25.1 - 165)

Last folate and B12 results

Have you been taking daily vitamin B complex since this result

thyroidqueen12 profile image
thyroidqueen12 in reply to SlowDragon

I have not taken any supplements. I am trying to change one thing at a time so that I know what is working. I was hoping to get my vitamins tested again to know how this has developed. Annoyingly, the NHS would not test my vitamins again as they said they were in range last time I got tested 😱

SlowDragon profile image
SlowDragonAdministrator in reply to thyroidqueen12

supplementing a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.

This can help keep all B vitamins in balance and will help improve B12 levels too

Difference between folate and folic acid

chriskresser.com/folate-vs-...

Many Hashimoto’s patients have MTHFR gene variation and can have trouble processing folic acid.

thyroidpharmacist.com/artic...

B vitamins best taken after breakfast

Thorne Basic B or Jarrow B Right are recommended options that contains folate, but both are large capsules. (You can tip powder out if can’t swallow capsule)

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

Thank you, I will get one of these two. Do I take 1 tablet a day?

In short your FT3 labs are consistently lowThe consequence of this is poor health

T3 is the active thyroid hormone required by every cell in the body.

It is required in a consistent and adequate supply.

The supply available to your body is neither

Your T4/T3 conversion is impaired...

Low FT3 in relation to high(er) FT4 level

A Dio2 test would confirm ( or not) the presence of the Dio2 snp

A positive test may help convince an endo to prescribe T3

But your labs already indicate impaired conversion!

Heterozygous = impaired conversion

Homozygous = greater impact on conversion

Result...poor health.

Additionally, you have Hashi's ..

So thyroid levels can fluctuate

Are you GF?

An increase to 150mcg levo may, by conversion, help increase FT3

Your FT4 still has room in the lab range to increase levo dose

You will not be overmedicated so long as FT3 remains within lab range

If no improvement follows...

Then, I would suggest the addition of a little T3

thyroidqueen12 profile image
thyroidqueen12 in reply to DippyDame

Hi DippyDame,

Thanks for your message. Yes this is now the 3rd example of low conversion, and I will make sure to point this out to endo.

My endo said he would be reluctant to raise my levo again due to my weight. I am leaning towards having T3 added to my T4, rather than NDT because it is a smaller change. I'm worried that changing completely to NDT might make me feel worse again.

I am not currently GF, I have not found any issue with gluten. However, I am getting a coeliac blood test this week to check. (I saw on NICE guidelines that you can get this if you have hypothyroidism, so I thought it would be good to make sure!)

thyroidqueen12 profile image
thyroidqueen12 in reply to thyroidqueen12

I also forgot to ask:

What is the cause of FT4 percentage through range decreasing? Does this mean anything?

Feb conversion:

FT4: percentage through range : 62%

FT3: percentage through range: 29.73%

March conversion:

FT4: percentage through range 78%

FT3: percentage through range 48.65%

April conversion:

FT4: percentage through range: 45%

FT3: percentage through range of 36.11%

SlowDragon profile image
SlowDragonAdministrator in reply to thyroidqueen12

Possibly night time dosing is improving uptake and conversion

DippyDame profile image
DippyDame in reply to thyroidqueen12

Was this meant for me?

Hashi's can cause thyroid hormone levels to fluctuate.Since I don't have Hashi's I'll leave further comment to those with more experience

Good luck

DippyDame in reply to thyroidqueen12

Your weight gain is possibly exacerbated by low T3.

I lost about 2 stone when I changed to T3-only....but with RTH/high T3 dose I may be a bit of an exception!

If your endo doesn't want to increase your levo/T4 for whatever his reason may be, then why is he considering NDT (T4 + T3) which will also raise T4 level.

His joined up thinking is questionable!

It's not so much to do with degree of change as about getting the correct dose of the correct hormone.

Hashi patients don't necessarily have to be coeliac to find gluten a problem....but wise to check anyway.....your antibodies are high.

The immune system attacks the thyroid gland which becomes inflamed then cannot produce adequate hormones, resulting in hypothyroidism.

Gluten can trigger symptoms.

Avoid soya.

You can now present your case for T3 to your endo!!

jgelliss in reply to DippyDame

DippyDame sound advice. I added 10 mcg T3 to my 125 mcg T4 and the T3 raised my T4 high. Yet my FT3 was on the lower end. Very interesting. I was surprised to see it.

DippyDame sorry if I wasn't clear- I didn't mean that I am overweight. I am a normal weight. I meant that he is looking at your body weight when dosing levo

SlowDragonAdministrator in reply to thyroidqueen12

You don’t need any obvious gut issues to find that gluten is significantly affecting absorption of thyroid hormones

It’s always worth trying strictly gluten free diet, after coeliac test
