No range on Ft4

Was test done early morning and last dose levothyroxine 24 hours before test

How much levothyroxine are you taking

Do you always get same brand at each prescription

Ft3 obviously low

Likely low vitamin levels

Do you have autoimmune thyroid disease - Hashimoto’s

what vitamin supplements are you taking

When were vitamin levels last tested

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

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

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

If you can get GP to test vitamins then cheapest option for just TSH, FT4 and FT3 and includes BOTH TPO and TG antibodies -£29

Only do private testing early Monday or Tuesday morning.

T4 17.8

T3 4.3 range 4.0-6.6 = 11.54% - is this Free T3 or Total T3? Whichever it is it's very low. You may be looking at poor conversion of T4 to T3 but need to know if FT4 and FT3 were tested (rather than Total T4 and T3) and the range for the T4 result.

You haven't given a range for T4 so you'll have to work that out yourself with the calculator.

Feeling irritable, looking up says clinical depression, definitely hope not.

Where have you looked that up? Don't rely on Dr Google, there are many reasons for being irritable.

Gp won't refer me back to endo.

If results in range then endo would very likely refuse referral anyway.

In a previous post you said your TPO antibodies were 444, this confirms autoimmune thyroid disease aka Hashimoto's and it's common for levels and symptoms to fluctuate with Hashi's.

Thank you so much for getting back to me, yes dr Google.Thank you, at least I know i am not going mad.

What is the treatment for hashimoto disease please

No the GP never tests anything but the basics The T4 no range on the results on patient access.

Not had any feedback on the results, just looking on my patience access.

I take it i wait a year for another blood test

Thank you so much for your help

Many thanks Lisa

What is the treatment for hashimoto disease please

Hashi's is the most common cause of hypothyroidism. There is no treatment for Hashi's, it's the resulting hypothyroidism that's treated.

Some people find a gluten free diet helps but there's no guarantee. Gluten contains gliadin (a protein) which is thought to trigger autoimmune attacks so eliminating gluten can help reduce these attacks.

You don't need to be gluten sensitive or have Coeliac disease for a gluten free diet to help.

Gluten/thyroid connection: chriskresser.com/the-gluten...

Some information about Hashi's:

stopthethyroidmadness.com/h...

stopthethyroidmadness.com/h...

hypothyroidmom.com/hashimot...

thyroiduk.org.uk/tuk/about_...

Supplementing with selenium l-selenomethionine 200mcg daily is said to help reduce the antibodies, as can keeping TSH suppressed.

Some people find cutting out dairy can help.

You need to know if your conversion is poor. Contact the surgery and find out the range for the T4 and please confirm that these tests are FT4 and FT3 and not Total T4 and T3. I imagine they are FT4/FT3 but we need to know for certain to know that we are giving you the correct advice, the devil is in the detail!

Come back with this information and we may be able to help further.

HiIt Is a free T3

Free T4 range 11-26

SlowDragon profile image
SlowDragonAdministrator in reply to Lisajane747

so you have room for increase in Levothyroxine

Suggest increasing by 12.5mcg initially

Accord don’t make 25mcg tablets

Cut 50mcg in 1/4 to add 12.5mcg

Easy to cut with sharp craft scalpel

Store remaining 1/4’s for next days

Get coeliac blood test (about £10 online) before cutting gluten out completely

Retest thyroid levels 6-8 weeks after any dose change or diet change

5% test positive for coeliac…..but further 81% find gluten free diet significantly improves symptoms or is essential

About 50% find dairy free diet helps too

TSH: 0.10 (0.38-5.34)

FT4: 17.8 (11-26)

FT3: 4.3 (4.0-6.6)

So we have FT4 at 45% through range with FT3 at 11.54% through range.

To know how well we convert we need TSH to be 1 or below then look at the FT4 and FT3. Your TSH is low yet your FT4 is still below half way through range. This suggests you could increase your Levo but getting your GP will agree with such a low TSH might be difficult, they don't like seeing TSH below range.

Your FT4/FT3 does show poor conversion and even if you increase your Levo and get a higher FT4 it's very likely that your FT3 wont increase much. Ideally they would be reasonably well balanced on Levo only.

Vit levels were all okay in last 3 months.

What exactly were the results/ranges? Optimal levels are:

Vit D: 100-150nmol/L

B12: top of range for Total B12, if Active B12 tested then over 100

Folate: at least half way through range

Ferritin: some experts say the optimal ferritin level for thyroid function is 90-110ug/L

If these aren't optimal then it can affect conversion of T4 to T3.

Multi _max woman from natures best has vit b12, magnesium, b6 and mult b complex

Multi-max Woman or Multi-max Woman 50+?

I would ditch this. Multi's aren't recommended here. They contain too little of active ingredients to help low levels or deficiencies, they often use the wrong form of the vitamins, and they also often contain things we shouldn't supplement unless tested and found to be deficient. Also too many different vitamins/minerals taken together means that not all can be absorbed and some should never be taken together.

The Multi-max Woman contains Vit K1 - this is the wrong form. This is the blood clotting form and should never be taken by anyone on blood thinners or at risk of blood clots. I expect they don't caution about this. It is Vit K2 that is the form more suited to a multi.

They both contain folic acid and cyanocobalin (B12), these are the wrong forms, the better bioavailable forms are methylfolate and methylcobalamin.

The magnesium they contain is the oxide form which is for constipation.

They contain iron which must be taken 2 hours away from any other supplement as it affects their absorption.

They contain zinc and copper. We hypos are often high in one and low in the other, so we should test before supplementing to find out what we need.

They include the selenite form of selenium which should be avoided, the recommended form is selenium l-selenomethionine.

They contain iodine at the recommended daily amount. We should not supplement iodine without first testing to see if we need it. Iodine is easily obtained from a UK diet from milk, yogurt, cod, haddock, scampi, etc. Iodine solution used to be used to treat overactive thyroid so can make hypothyroidism worse or cause hypothyroidism. It's said that when Hashi's is present it should not be used.

Best to test key nutrients and only supplement with what is needed to bring up to optimal levels then dose to maintain.

Hi, I would suggest getting your sex hormones checked as these start dropping well before menopause and can make you feel utterly awful with many crossover symptoms with hypo

"Have fibromyalgia and osteoarthritis, positive rheumatoid factor"

I think there is a strong link with all of these conditions and low estrogen?
