help with blood test results…

12 Replies

Hi,

I’ve been taking levothyroxine (125mcg) for an underactive thyroid for 3 years. Had a private test done and got the results today.

My TSH is 0.52 (range 0.27 - 4.20) and anti-thyroidperoxidase is 94 (normal range less than 34).

Everything else was in normal reference range as per the image. Can anyone help me to interpret this?

Welcome to the forum

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

Which brand of levothyroxine are you taking

Do you always get same brand at each prescription

Did you know you have autoimmune thyroid disease also called Hashimoto’s diagnosed by high thyroid antibodies

Assuming you are not already on strictly gluten free diet, request GP run coeliac blood test, unless already been tested

hi,

test was done at 10am with last dose of levothyroxine at 6am (it wasn’t indicated that I needed to refrain from taking it unfortunately!)

The brand is Wockhardt (not sure if I’ve had different brands in the past to be honest I’ve never noticed!)

I had no idea about any potential hashimotos until I had these results (it was suspected which is why I had the private test done). Definitely not on a gluten free diet yet but will switch to one now.

Thanks for your help!

So your Ft4 is falsely high as last dose levothyroxine was only 4 hours before test

How much lower it would have been after 24 hours impossible to say

FT3: 4.3 pmol/l (Range 3.1 - 6.8)

Ft3 is only 32.43% through range

Work on improving low vitamin levels and retest again correctly in another 8 weeks

Gluten Free Diet likely to improve absorption of levothyroxine

The brand is Wockhardt

Wockhardt only make 25mcg tablets

Are you on 5 x 25mcg tablets per day

Jemmawilliams in reply to SlowDragon

I have 100mcg tablet too but there’s no clear brand name I can see on the box! Having looked more closely there’s an address which says ‘Accord’, perhaps this is it?

SlowDragon profile image
SlowDragonAdministrator in reply to Jemmawilliams

yes Accord

Most easily available (and often most easily tolerated) are Mercury Pharma or Accord

Mercury Pharma make 25mcg, 50mcg and 100mcg tablets 

Mercury Pharma also boxed as Eltroxin. Both often listed by company name on pharmacy database - Advanz

Accord only make 50mcg and 100mcg tablets. Accord is also boxed as Almus via Boots, 

Wockhardt is very well tolerated, but only available in 25mcg tablets. Some people remain on Wockhardt, taking their daily dose as a number of tablets

vitamin levels

Ferritin is extremely low, virtually deficient

Request GP do full iron panel test for anaemia or test via Medichecks

Folate far too low

Vitamin D insufficient

What vitamin supplements are you currently taking

Improving low vitamin levels can significantly improve conversion rate of Ft4 to Ft3

Jemmawilliams profile image
Jemmawilliams in reply to SlowDragon

is there a particular vitamin that can be recommended based on my levels? I’ve done research online but conscious of maintaining a balance based on my own blood work!

SlowDragon profile image
SlowDragonAdministrator in reply to Jemmawilliams

To improve low folate

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

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

Difference between folate and folic acid

healthline.com/nutrition/fo...

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 recommended vitamin B complex that contains folate, but they are large capsules. (You can tip powder out if can’t swallow capsule)

Thorne currently difficult to find at reasonable price, should be around £20-£25. iherb.com often have in stock. Or try ebay

Other options

healthunlocked.com/thyroidu....

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

endo.confex.com/endo/2016en...

endocrinenews.endocrine.org...

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg)

only add one supplement at a time then wait 2 weeks to assess before adding another

vitamin D

GP will often only prescribe to bring vitamin D levels to 50nmol.

Some areas will prescribe to bring levels to 75nmol or even 80nmol

leedsformulary.nhs.uk/docs/...

GP should advise on self supplementing if over 50nmol, but under 75nmol (but they rarely do)

mm.wirral.nhs.uk/document_u...

But with Hashimoto’s, improving to around 80nmol or 100nmol by self supplementing may be better

pubmed.ncbi.nlm.nih.gov/218...

vitamindsociety.org/pdf/Vit...

Once you Improve level, very likely you will need on going maintenance dose to keep it there.

Test twice yearly via NHS private testing service when supplementing

vitamindtest.org.uk

Vitamin D mouth spray by Better You is very effective as it avoids poor gut function.

There’s a version made that also contains vitamin K2 Mk7.

One spray = 1000iu

It’s trial and error what dose we need, with thyroid issues we frequently need higher dose than average

Low ferritin

Don’t take anything ….yet

You need to get full iron panel test for anaemia first

It’s possible to have low ferritin but high iron

cks.nice.org.uk/topics/anae...

Serum ferritin level is the biochemical test, which most reliably correlates with relative total body iron stores. In all people, a serum ferritin level of less than 30 micrograms/L confirms the diagnosis of iron deficiency.

Never supplement iron without doing full iron panel test for anaemia first and retest 3-4 times a year if self supplementing.

Medichecks iron panel test

Test early morning and fasting

medichecks.com/products/iro...

Meanwhile Look at increasing iron rich foods in diet

Eating iron rich foods like liver or liver pate once a week plus other red meat, pumpkin seeds and dark chocolate, plus daily orange juice or other vitamin C rich drink can help improve iron absorption

List of iron rich foods

Great in-depth article on low ferritin

oatext.com/iron-deficiency-...

This is interesting because I have noticed that many patients with Hashimoto’s disease and hypothyroidism, start to feel worse when their ferritin drops below 80 and usually there is hair loss when it drops below 50.

Your antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

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 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

Hashimoto’s and leaky gut often occur together
