t3 only high tsh

[Maffster08]

Switched to t3 only 40mcg dose split

Recent blood tests show

Ft3. 4.1. Range. 3.1 - 6.8

Ft4. 0.9. Range. 12 -12

Tsh. 105. Range. 0.27. - 4.20

4 years ago when on same protocol tsh would be in range … why tsh so high now ?

Just had it ultrasound scan first time as neck swells up & down..

Snoring incredibly too.

Which brand of T3

Has this changed recently

40mcg isn’t much if on T3 only

60mcg is more typical

Try increase by 5mcg initially

Thybon

Your TSH is 105 - one hundred and five? On 40 mcg T3? That has got to be a mistake, some sort of interferrence in the assay, mouse antibodies or something. You need to get a retest in a different lab that uses different testing methods. That cannot be right.

What are 'mouse antibodies' GG?

[greygoose in reply to TiggerMe]

Anti-TSH antibodies. Diogenes always called them mouse antibodies.

[greygoose in reply to Maffster08]

OK, but were they done in the same lab, or two different labs?

[Maffster08 in reply to greygoose]

Ones a private company, ones nhs so yes different labs…I’ll post when ive found what endos thoughts are…

Nothings ever straightforward with hashimoto’s
