Medichecks result - different to NHS

CherryPie2 profile image
9 Replies

Hi,

Got round to a Medichecks test for thyroid. I know I'm Hashi.

TSH 5.9 mIU/L (Range 0.27 - 4.2)

FREE T3 4.2 pmol/L (Range 3.1 - 6.8)

T4 15.6 pmol/L (Range12 - 22)

Interestingly the NHS TSH test I had just a week before (taken same time of day) was 3.01 mIU/L (Range 0.27 - 4.2)

My NHS endo has discharged me based on that - good riddance - waste of my time.

I've been on 75mcg and 100mcg alternating days Levo since Aug - feel MUCH better.

However the above suggests I need more Levo? I don't really understand the T3 as never had that tested - it is in range but should be higher - as per the T4 - is that right? Or do i need to look at getting T3?

....

Yes all vits are low despite supps :(

Yes you need next increase in Levo

Free T4 (fT4) 15.6 pmol/L (12 - 22) 36.0%

Free T3 (fT3) 4.2 pmol/L (3.1 - 6.8) 29.7%

Initially perhaps only increase to 100mcg daily while working on low vitamin levels too

NHS TSH test I had just a week before (taken same time of day) was 3.01 mIU/L (Range 0.27 - 4.2)

Even on NHS test you should have been increased

approx how much do you weigh in kilo

Even if we frequently start on only 50mcg, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until eventually on, or somewhere near full replacement dose (typically 1.6mcg levothyroxine per kilo of your weight per day)

cks.nice.org.uk/topics/hypo...

bnf.nice.org.uk/drugs/levot...

nhs.uk/medicines/levothyrox...

Adults usually start with a dose between 50 micrograms and 100 micrograms taken once a day. This may be increased gradually over a few weeks to between 100 micrograms and 200 micrograms taken once a day.

Some people need a bit less than guidelines, some a bit more

TSH should be under 2 as an absolute maximum when on levothyroxine

gponline.com/endocrinology-...

Graph showing median TSH in healthy population is 1-1.5

Comprehensive list of references for needing LOW TSH on levothyroxine

healthunlocked.com/thyroidu....

onlinelibrary.wiley.com/doi...

If symptoms of hypothyroidism persist despite normalisation of TSH, the dose of levothyroxine can be titrated further to place the TSH in the lower part of the reference range or even slightly below (i.e., TSH: 0.1–2.0 mU/L), but avoiding TSH < 0.1 mU/L. Use of alternate day dosing of different levothyroxine strengths may be needed to achieve this (e.g., 100 mcg for 4 days; 125 mcg for 3 days weekly).

sciencedirect.com/science/a...

The optimal daily dose in overt hypothyroidism is 1·5–1·8 μg per kg of bodyweight, rounded to the nearest 25 μg.

Which brand of Levo are you taking

Do you always get same brand at each prescription

Vitamin levels are low BECAUSE you are still not on high enough dose Levo

Exactly what vitamin supplements are you taking

You need full iron panel test for anaemia

High CRP - test for inflammation……is high. This usually falsely raises ferritin levels….so ferritin may actually be lower than 30

Are you on Gluten Free and/or dairy free diet

You are wonderful SlowDragon thank you for replying.

Do you think I need to investigate T3 at this stage or work on Lev increase?

Have details of private Endo that will look to prescribe T3 if needed.

“Even on NHS test you should have been increased”

But instead the Endo discharged me :( know I need to get under 2 on medication but GP or Endo don’t seem to know this. Will take print outs to GP and try.

I’m about 58kg (and increasing weekly it seems - packing on weight) - so should have started 92.8 (started on 25mcg) - I’m on daily average 86mcg now and sure feels better.

…..

On Teva - doesn’t seem to offer any issues other than TSH is still high but that’s dose issue.

Yes Gluten free since summer and almost Dairy free but will be 100% off it.

…..

“Vitamin levels are low BECAUSE you are still not on high enough dose Levo” - I thought this. I’m rattling and my wallet is taking a pounding with all these vits.

11am Vit D3000 & K2 Better you Spray and

IRON 10mg Better You Spray

...

Post Dinner:

High potency Fish Oils 330mg of EPA and 220mg of DHA x 2

Magnesium Bisglycinate 600mg x 2

Zinc Citrate 15mg

Vitamin B12 1000µg

Tumeric and 10µg of vitamin D

Probiotic

Anything I should tweak here? Full B Complex maybe?

Your folate is less than 50% of range so yes a good B complex you could switch out for the stand alone B12.

B complex suggestions: Slightly cheaper options with inactive B6:

amazon.co.uk/Liposomal-Soft...

Contains B6 as P5P an active form:

Do you have any links to papers or info that says folate should be 50% or more through range? Is this an age dependent thing, or does it apply to everyone?

Jaydee1507 profile image
Jaydee1507Administrator in reply toStitchFairy

I can only find papers linked to neural tube defects from low which arent really that relevant but folate often needs to be ear the top of the range.

sciencedirect.com/science/a...

I'm unsure how age would affect the bodies requirement for folate. People with MTHFR genes often require more.

I know folate needs to be good in pregnancy, but I thought maybe you had some info about it needing to be above 50% for most people. 🙂

Jaydee1507Administrator in reply toStitchFairy

People with hypothyroidism need good levels of all vitamins so their bodies can use thyroid hormone well. Reference ranges for folate vary between labs but a minimum good level would be 50% of range and ideally a lot higher.

Full Iron panel done May 24 - all low but just in range so got the "in range" shrug from GP. My diet is iron rich - it's an absorption issue I think prob down to low Levo as you said
