Thyroid Blood Results - Cause for Concern?

AdamW85 profile image
17 Replies

Good evening. I have been directed to this site from a Facebook group, due to a question I posed regarding some recent blood results.

I have earlier this week completed a range of bloods via Medicheck, to determine some key health markers. I had a call yesterday evening from a Dr reviewing the results expressing concern over the thyroid results, and suggesting I should visit my GP as soon as possible.

I do have the full results, but the thyroid ones of note are:

Thyroid stimulating hormone - <0.0005mIU/L

Free T3 - 9.9pmol/L

Free T4 - 34pmol/L

Some important points to note:

1) In terms of my health, I do feel very well. The test was purely out of interest, not on the back of any unusual symptoms. I do not take any medication whatsoever.

2) Along with other vitamin and mineral supplementation, I have for the past 4/5 years taken 2 drops of 15% Lugols Iodine daily in water.

Whilst waiting to see what the GP has to say, I thought it would be worth seeing what others think with regards to these results. I'm not expecting any formal guidance as such, just others experiences with regards to these particular markers, and whether it has been cause for concern.

E.g. is taking the Iodine likely to be causing these results? Particularly as I did have the Iodine the morning of the blood draw (draw at 2pm - fasted all morning).

E.g. although figures are considered 'high' and 'out of range', are they actually ok?

I would also be interested in hearing about any Dr that specialise in this area, or generally natural health orientated.

Any info would be greatly appreciated.

You say Along with other vitamin and mineral supplementation. Suggest you should consider biotin:

The time at which blood is drawn for tests can be important:

The numbers, if they reflect reality, are concerning. High thyroid hormone levels can be dangerous. And those numbers would usually indicate a level of hyperthyroidism. And could suggest Graves disease, a toxic multinodular goitre, or some other issue.

However, the topic I've avoided so far, the iodine could indeed be a major contributor. Whilst iodine is essential for your thyroid to produce thyroid hormone, an excess can have many consequences. And they are not always easy to understand.

One 15% Lugol's solution I found says each drop contains 16095 micrograms of iodine. Which is 107.3 times the 'official' recommended intake. Two drops, of course, would double that.

While I am happy to accept that 150 micrograms is arguably too low, I cannot believe it is safe to consume 32190 micrograms a day.

The Japanese are often held up as the largest consumers of iodine. Last I read, an assessment of the real intake in Japan came to the conclusion that the average is around 3000 micrograms. That is, less than a tenth of what you have been taking.

And the Japanese have higher rates of some thyroid disorders such as Hashimoto's than do we.

The direct and immediate effect of high iodine intake on thyroid hormone levels will vary considerably from one person to another. But I think you have to look at where you are and consider what you want to do.

Incidentally, we have a number of members who have suffered from things like taking amiodarone - a medicine which contains a lot of iodine. And it can take several months to really start to recover.

Thank you for the reply. I am not knowingly taking any biotin supplements. The supplements I take daily are (which contain zero Biotin):

Vitamin C (Ascorbic Acid) - 5g

Multi Mineral Mix - 5g - (salesatdrmyhill.co.uk/multi...

Magnesium - 2 capsules (british-supplements.net/pro...

Zinc - 1 capsule (british-supplements.net/pro...

Tongkat Ali - 1 Capsule (british-supplements.net/pro...

Vitamin K2 - 2 Capsules (terranovahealth.com/product...

My diet is generally high in meat, and eggs a few times a week. So possibly this has skewed it.

The multi mineral mix contains another 300mcg of iodine, also why double the dose of the K2 capsules?

AdamW85 profile image
AdamW85 in reply toTiggerMe

Based on feedback that can safely take up to 2 capsules to help with Vitamin D absorption

TiggerMe profile image
TiggerMeAmbassador in reply toAdamW85

If you are only getting the 1000iu Vit D then 10mcg of K2 is adequate, magnesium helps with the uptake of Vit D.... K2 helps to send the calcium to teeth and bones etc rather than clogging up arteries

Your Vit D level isn't too bad aiming for 100-150nmol/L

TiggerMe profile image
TiggerMeAmbassador in reply toTiggerMe

Edit... just re-read you are taking 5g of the mix and contents are listed per g so you are taking just from this 1500mcg iodine also 30mg Zinc along with 246mg assuming you take one of the zinc blend?

Zinc and copper need to be balanced as one being high will lower the other so you really need to test

5000iu of Vit D so 50mcg of K2 would be adequate

TiggerMe profile image
TiggerMeAmbassador in reply toTiggerMe

The K2 also contains freeze dried kale which being a goitrogen may inhibit uptake of iodine, which in your case is no bad thing but something to be aware of I've no idea how potent 300mg of it would be compared to fresh kale but uncooked is certainly more of an issue

You need to take these results to your GP

Stop all iodine

Exactly what other vitamin supplements are you taking

Biotin can falsely affect test results. stop any supplements that contain biotin 5-7 days before any blood test

GP will want to retest levels

Request GP also test TSI or Trab antibodies to see if you have Graves’ disease (autoimmune hyperthyroid)

Also test vitamin D, folate, B12 and ferritin

Link about Graves’ disease

thyroiduk.org/hyperthyroid-...

Graves Disease antibodies test via Medichecks

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

Thanks for the info. The test you suggest above are all showing ok. See attached pics.

I am wondering if the timing of the test, plus the fact I had iodine the morning of the test, is part of the problem

Upon waking I had my usual 2 drops of Iodine in water. No food, only water thereafter, until the test at 2pm.

Could be Graves’ disease

Your high TG antibodies suggests autoimmune disease

Could be early stage Hashimoto’s or Graves’ disease

Or it could be your large iodine supplement

Supplementing iodine frequently can cause problems

Never recommended on here

niddk.nih.gov/health-inform....

What causes hyperthyroidism?

Hyperthyroidism has several causes, including

Graves’ disease

overactive thyroid nodules

inflammation of the thyroid gland, called thyroiditis

too much iodine

too much thyroid hormone medicine

a noncancerous tumor of the pituitary gland

Welcome aboard,

These results show you have Hyperthyroidism and really do need to get it looked into, worth presenting these results to your GP who will run more tests.... the fact you have been taking iodine, which could be the cause, means you really need to stop taking the drops.... why were you taking them?

Do you have thyroid antibodies results?

Yes, your levels are certainly high enough to cause concern for your heart and bone health and need lowering

AdamW85 profile image
AdamW85 in reply toTiggerMe

Thanks for reply. See results below for antibodies. I do not understand the thyroglobulin antibody. It suggest a high marker in this (which mine is showing) should result in under-producing thyroid hormones. Mine are also showing high?

I was taking the Iodine on the back of reading multiple books and listening to multiple sources about the lack of Iodine in the western diet and soil, and the importance Iodine has in terms of our overall health.

antibodies

TiggerMeAmbassador in reply toAdamW85

These raised levels show that your thyroid is under attack caused by autoimmune reaction which means the body attacks itself, these could mean Hashimoto's which can cause high and low thyroid levels or it could also mean Graves which results in high levels, your GP will run TRAb antibodies test and possibly start to treat you or refer you to an Endocrinologist

AdamW85 in reply toTiggerMe

Ok thank you.

Do you think as a result of the iodine? Is stopping Iodine likely to reverse these to normal levels?

TiggerMe profile image
TiggerMeAmbassador in reply toAdamW85

You are taking a huge amount of iodine which could well have triggered the over production of thyroid hormones whether it triggered the autoimmune reaction I couldn't say as it's hard to know what triggers these thinks, it can be stress, trauma, child birth maybe an accident or the body getting confused by gluten or dairy 🤷‍♀️
