Help with latest Blood Test

Bright-eyes profile image
8 Replies

Hello, I’m hoping someone can give some advice on latest blood test please.

I am on 100mgs Levothyroxine. I did trial T3 but didn’t notice much difference by taking T3really. Im not sure if this is because I wasn’t on a high enough dose of L4 at the start of trialing it.

I have taken the D1o2 test and my T4 to T3 is compromised by one parent which is why I wanted to trial it, but was only on 50mgs of levothyroxine at that time.

I am still experiencing a lot of aches in my legs which feel heavy. I am taking vit C, omega 3,6,7 & 9. Vit B complex (Thorne) & magnesium malate. All vitamins by reputable companies.

TIA…Sharon.

You can edit your post to add results by pressing the ‘more’ key under the blue reply button at the bottom of your post.

I notice that 5 months ago (on 75mcg Levo and 10mcg Lio) your results were

0.2 TSH

15.4 FT4

4.9 FT3

Was FT3 not tested this time?

How long have you been taking 100mcg Levo only? Looks like you will need to add a further 25mcg Levo.

What time of day was this test?

When did you last take Levo before the test?

Your FT4 is only at 35% of its range and needs to be a lot higher to 70%+.

Really you need to see an FT3 to decide if you are converting or not.

Suggest you get a private test run. See link for companies offering private blood tests & discount codes, some offer a blood draw service at an extra cost. thyroiduk.org/testing/priva...

There is also a new company offering walk in& mail order blood tests in London, Kent, Sussex & Surrey areas. Check to see if there is a blood test company near you. onedaytests.com/products/ul...

Only do private tests on a Monday or Tuesday to avoid postal delays.

Are you taking vit D as well?

When did you last test vitamins?

Thankyou for your reply.

Bloods were taken 8.30am. Levothyroxine not taken 24 hrs before. Bloods taken on the nhs hence no T3 recorded

I haven’t been taking my vit d for a while but will start this again.

Will also get a vitamin levels checked.. anyone know best company to do this with please?

Will also get bloods checked privately for T3 levels.

Should I also talk to my Gp about an increase in Levothyroxine? If so, do you think they would allow an increase with these results?

Thx. Sharon.

So your results show stable blood levels of T4 and highest TSH.

You my struggle to get GP to increase due to your TSH. You can show them the NICE guidelines wher eit states an approx starting dose of Levo by weight with this calculation:

1.6 x weight in kilos = Levo dose.

Probably the cheapest for vitamins would be Randox or MMH. You could also get an FT3 run while you're there.

Request next dose increase in levothyroxine to 125mcg

Retest again in another 6-8 weeks

And get vitamin levels tested at next test
