So my daughter had her bloods done last week they failed to do ft4 which is annoying but others

Tsh0.01. (0.35-5.5)

Ft3 6.6 (3.5-6.5)

She had bloods at 4 pm and did not take thyroid tablet they saying she should reduce dose but she doesnt want to as doesnt feel over medicated .Her last bloods she hd took was again at 4pm i know not a good time bit only tome we could go and this time shes took her tablet a few hours before

Tsh 0.01(0.35-5.5)

Ft3 6.2 (3.5-6.5)

Ft4 19 (9-16)

The results were pretty much similar !

Can we argue why results for tsh verg low?

What is your daughter taking at the moment? And how long a gap did she leave between her last dose and the blood draw?

jwoodward5 profile image
jwoodward5 in reply to greygoose

Her last levo 12 .30 day before .

greygoose in reply to jwoodward5

OK, so slightly over the recommended 24 hours. And she's only on 100 mcg levo? Does she have Hashi's?

jwoodward5 profile image
jwoodward5 in reply to greygoose

We dont think she has it? What are the signs?

greygoose profile image
greygoose in reply to jwoodward5

Who doesn't think she has it? Her doctor? Why doesn't he just test for it and find out? She needs her TPO antibodies tested.

Although, I have to say, a negative result for antibodies is not conclusive, because antibodies fluctuate all the time, and you would need several tests to be sure. Even then, you can have Hashi's without ever having raised antibodies. But, a sure sign of having it is when blood levels appear to jump around independantly of the dose. And seeing someone with an FT3 over the top of the range on just 100 mcg levo should make anyone suspicious. Could very well be that she's coming down from a Hashi's 'hyper' swing.

One word of caution, doctors in the UK do not call it Hashi's. They call it Autoimmune Thyroiditis - which it is, of course, but why they found it necessary to change the name when the rest of the world calls it Hashi's, is anyone's guess. He probably has no idea what 'Hash's' is. :)

Her tpo was negative yes so we assumed she disnt have that . Dont suppose theres anytbing u can do anyway

greygoose in reply to jwoodward5

There's not much you can actually do about Hashi's, there's no cure, but it's good to know because it explains strange blood test results. Do you know how Hashi's works?

One negative TPOab test cannot completely rule out Hashi's, as I explained above. Could she ask for an ultrasound of her thyroid, that might give some clues?

jwoodward5 profile image
jwoodward5 in reply to greygoose

Not sure how hashi works no . She has previuosly had an ultrasound of thyroid it showed nothing even though she has a lump in that area they said just fatty tissue

greygoose profile image
greygoose in reply to jwoodward5

OK, so Hashi's is an autoimmune disease, where the immune system attacks and slowly destroys the thyroid.

After every attack, the dying cells release their stock of thyroid hormone into the blood stream, causing the levels of the Frees to shoot up - FT4 to around 30/40 something, FT3 around 11/12 - and the TSH therefore drops to suppressed.

There is no knowing how long these high levels will persist, but eventually, they will drop by themselves as the excess hormone is used up or excreted, and not only will you become hypo again, but slightly more hypo than before, because there is now less thyroid to make hormone.

Therefore, it's very important that your doctor does not reduce your prescription, because you’re going to need it again! If you start to feel over-medicated at that point - some do, some don't - the best thing is to stop levo for a few days, then, when you feel hypo again, start taking it again. It's very important to know one's body, and how it reacts.

There is no cure for Hashi's - which is probably one of the reasons that doctors ignore it - apart from the fact that they know nothing about it, of course!

However, between the 'hyper' swing, and the descent back into hypothyroidism, there can be a phase - quite a long one, sometimes - of normality, where the person is neither hypo nor 'hyper'. This is where people sometimes start talking of having 'cured' their Hashi's, by whatever means. But, it doesn't last. Eventually, you will go hypo again.

But, there are things the patient can do for him/herself to help them feel a bit better.

a) adopt a 100% gluten-free diet. Hashi's people are often sensitive to gluten, even if they don't have Coeliac disease, so stopping it can make them feel much better. Worth a try.

b) take selenium. This can help with conversion of T4 to T3 - something that Hashi's people often find difficult.

c) the best way to even out the swings from hypo to 'hyper' (often called Hashi's Flares, but that doesn't really sum up the way it works) is to keep the TSH suppressed. This is difficult because doctors are terrified by a suppressed TSH, for various false reasons, and because they don't understand the workings of Hashi's. But, TSH - Thyroid Stimulating Hormone (a pituitary hormone) - tries to stimulate the thyroid to make more hormone, but it also stimulates the immune system to attack. So, the less gland activity there is, the less immune system activity there will be, meaning less attacks, gland destruction slowed down and less swinging from hypo to hyper and back.

Thankyou for explaining that well she is on wheat therefore gluten free diet plus dairy free so thats one good thing

greygoose profile image
greygoose in reply to jwoodward5

Not sure what you're saying, there. Do you mean wheat-free diet? There are other sources of gluten.

100 mg levo

Lora7again profile image
Lora7again in reply to jwoodward5

That is a low dose

SlowDragon profile image
SlowDragonAdministrator

Looking at previous posts, presumably she has Hashimoto's

When were vitamin levels last tested?

What vitamin supplements does she currently take?

She needs to get vitamin D, folate, B12 and ferritin tested

These need to be optimal

Is she on dairy free diet?

If lactose intolerant is she on Teva Levothyroxine

Is she strictly gluten free?

jwoodward5 profile image
jwoodward5 in reply to SlowDragon

She is dairy wheat yeast and lactose free as intolerant her ferritin is over the highest range but docs say fine magnesium also at top end of range . Last time b12 vit d midrange . She didnt like teva so on levo 100mg activis

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

So Activis has lactose in

GP should prescribe liquid Levothyroxine

thyroiduk.org.uk/tuk/treatm...

B12 and folate need to be near top of range

Most Hashimoto's patients need to supplement to maintain optimal vitamin levels

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

chriskresser.com/folate-vs-...

B vitamins best taken in the morning after breakfast

Igennus Super B complex are nice small tablets. Often only need one tablet per day, not two. Certainly only start with one tablet per day after breakfast. Retesting levels in 6-8 weeks

Or Thorne Basic B or jarrow B-right are other options that contain folate, but both are large capsules

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before any blood tests, as biotin can falsely affect test results

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

endocrinenews.endocrine.org...

Vitamin D at least around 80nmol and around 100nmol may be better

Vitamin D mouth spray by Better You is good as avoids poor gut function.

It's trial and error what dose each person needs. Frequently with Hashimoto's we need higher dose than average

Why do u think she has hashimoto?

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

Hashimoto's (autoimmune thyroid disease) is the most common reason for being hypothyroid

Lactose and gluten intolerance extremely common with Hashimoto's

Diagnosed by high thyroid antibodies.

Presumably she has had thyroid antibodies tested?

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

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

About 90% of all primary hypothyroidism in Uk is due to Hashimoto's.

Low vitamins are especially common with Hashimoto's. Food intolerances are very common too, especially gluten and lactose intolerance

So it's important to get TPO and TG thyroid antibodies tested at least once .

In past had these antibodies tested and were ok . She is lactose intol but not gluten only wheat

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

Has she had BOTH TPO and TG thyroid antibodies tested

NHS refuses to test TG antibodies if TPO antibodies are negative.

Many people only have raised TG antibodies

You would need to test both TPO and TG antibodies privately via Medichecks or Blue Horizon

20% of Hashimoto's patients never have raised antibodies. Has she had ultrasound scan of thyroid?

jwoodward5 profile image
jwoodward5 in reply to SlowDragon

Just tpo then but was in range yes thyroid gland scanned nothing . Are those bloods ok ? Can she continue on 100 levo

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

Obviously she needs to remain on Levothyroxine

But it's very important to have all four vitamin levels optimal. This helps improve the way thyroid hormones are used. Meaning she's less likely to get dose Levothyroxine reduced

If vitamin levels are low TSH tends to drop and GP starts hassling to reduce Levothyroxine

Would recommend getting both TPO and TG thyroid antibodies tested privately plus TSH, FT3 and FT4 (and vitamins if GP won't test)

medichecks.com/products/thy...

Plus vitamins

medichecks.com/products/thy...

Important to get blood test as early as possible in morning before eating or drinking anything other than water and last dose Levothyroxine 24 hours prior to blood test

Come back with new post once you get results

jwoodward5 profile image
jwoodward5 in reply to SlowDragon

Ok will try

Lora7again in reply to jwoodward5

What do you mean by ok?

SlowDragon profile image
SlowDragonAdministrator

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .

Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).

This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)

Recommend she gets full Thyroid and vitamin testing at correct timing .....privately if necessary

Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies

thyroiduk.org.uk/tuk/testin...

For thyroid including antibodies and vitamins

Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random

Cheapest option for just TSH, FT4 and FT3 £29 (via NHS private service )

She should have had her bloods done first thing not at 4pm ... TSH changes once we eat I thought everyone knew this.

jwoodward5 profile image
jwoodward5 in reply to Lora7again

Does tsh get higher or lower after food?

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

TSH has a strong diurnal variation. It's highest in early morning and drops through the day

TSH drops after eating too

jwoodward5 profile image
jwoodward5 in reply to SlowDragon

So low tsh could be due to late time of test and haven eaten

SlowDragon profile image
SlowDragonAdministrator in reply to jwoodward5

Exactly

And low vitamins can cause low TSH too

So she should get full Thyroid and vitamin testing early morning before eating or drinking anything other than water and last dose Levothyroxine 24 hours prior to blood test

If taking any supplements that contain biotin (eg vitamin B complex) she should stop these a week before any blood tests. Biotin can falsely affect test results
