Blood Test Results

Hi, Could someone look over my latest blood test results from my GP.

I have followed all requirements before the test.

I should also let you know that I seen a private Endo to have a trial of T3 and had been advised to drop my T4 to 25 mgs ( from 75mg) and take 10 mgs of T3 each day.

I have been taking this dose for over 2 months at the beginning I didn’t feel too bad but now I feel exhausted come 2pm and have to sleep as soon as I get home from work at 5pm, not good as need to start dinner for my children.

I have been given another 2 months prescription for T3 but not sure if I should increase T3 or T4 ??

I will do a private BT from monitor my health to get my T3 results later this week.

Many Thanks

So you need to retest INCLUDING Ft3

Obviously just testing TSH and Ft4 is totally inadequate

FT4: 9.7 pmol/l (Range 7.9 - 16)

Ft4 only 22.22% through range

However you can see now Ft4 is now far too low

Do you always get same brand levothyroxine at each prescription

Which brand on levothyroxine

Which brand of T3

Do you split T3 as 2 x 5mcg

What were Ft4 and Ft3 before adding T3?

Suggest you consider increasing levothyroxine back to 75mcg daily and retest including Ft3 in 6-8 weeks

No ferritin result?

I sometimes get accord and sometimes wockhardt of levothyroxine. For T3 I get Teva. I don’t split T3.

I take T3 & T4 doses at 7am.

Ok. Thankyou. I have an Endo appointment on 22/12/23. But as I’m becoming more aware from posts on this forum it seems that Endo’s can be just as clueless as Gp’s when it comes to thyroid issues and medicating. 🤷🏻‍♀️

I will post private blood results when I get them.

Looking at previous post I am at a loss as to why on earth endocrinologist started you on T3

healthunlocked.com/thyroidu...

FT4: 10.2 pmol/l (Range 7.9 - 16)

Ft4 only 28.40% through range

And there wasn’t even a Ft3 result

You were clearly not on high enough dose levothyroxine and needed 25 mcg dose increase to 75mcg then retest

What were results 6-8 weeks after being on 75mcg levothyroxine

Vitamin levels

Ferritin was virtually deficient at 33

Quite likely Ferritin even lower now

Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)

On T3 - day before test ALWAYS split T3 as 2 or 3 smaller doses spread through the day with last dose 8-12 hours before test

Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

Testing options and includes money off codes for private testing

I can’t quite figure out why the private endo told you to drop your levothyroxine. You definitely weren’t overmedicated—in fact, your last post shows you to be undermedicated. You may not even have needed liothyronine if you’d been on enough levothyroxine—you weren’t on the right dose for you at that time.

Anyway. You are where you are, so let’s move from here. Are you due to see the private endo again?

25mcg levo and 10mcg liothyronine is very unlikely to be enough for anyone with hypothyroidism.

Obviously getting a full set of thyroid function tests is going to be important—we need to see your FT3 result—but I think you may actually end up needing more levothyroxine and more liothyronine.

Also notice you have propranolol listed in tags on your profile

Are you still taking propranolol, if yes how much

Propranolol slows uptake and conversion of Ft4 to Ft3 ….it’s frequently prescribed for HYPER thyroid patients for that reason

Propranolol also tends to lower magnesium

Looking through previous posts

Serum thyroid peroxidase antibody concentration 303 is/ml (0.0-35.0)

Your high TPO antibodies confirms cause of your hypothyroidism is autoimmune thyroid disease aka Hashimoto’s

About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies

Autoimmune thyroid disease with goitre is Hashimoto’s

Autoimmune thyroid disease without goitre is Ord’s thyroiditis.

Both are autoimmune and generally called Hashimoto’s.

Hashimoto's affects the gut and leads to low stomach acid and then low vitamin levels

Low vitamin levels affect Thyroid hormone working

Poor gut function can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten. Dairy is second most common.

A trial of strictly gluten free diet is always worth doing

Only 5% of Hashimoto’s patients test positive for coeliac but a further 81% of Hashimoto’s patients who try gluten free diet find noticeable or significant improvement or find it’s essential

A strictly gluten free diet helps or is essential due to gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and may slowly lower TPO antibodies

While still eating high gluten diet ask GP for coeliac blood test first as per NICE guidelines

nice.org.uk/guidance/ng20/c...

or buy test online for under £20, just to rule it out first

Assuming test is negative you can immediately go on strictly gluten free diet 

(If test is positive you will need to remain on high gluten diet until endoscopy, maximum 6 weeks wait officially) 

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

Non Coeliac Gluten sensitivity (NCGS) and autoimmune disease

pubmed.ncbi.nlm.nih.gov/296...

The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported

nuclmed.gr/wp/wp-content/up...

In summary, whereas it is not yet clear whether a gluten free diet can prevent autoimmune diseases, it is worth mentioning that HT patients with or without CD benefit from a diet low in gluten as far as the progression and the potential disease complications are concerned

restartmed.com/hashimotos-g...

Despite the fact that 5-10% of patients have Celiac disease, in my experience and in the experience of many other physicians, at least 80% + of patients with Hashimoto's who go gluten-free notice a reduction in their symptoms almost immediately.

Similarly few months later consider trying dairy free too. Approx 50-60% find dairy free beneficial
