Latest Results

Hi,

These are my latest results and am wondering what people think please.

I am still trying to get my T3 dose correct and currently taking T4 100mcg and T3 12.5mcg morning & 25mcg in the afternoon.

I feel much better but just wondering what others think. NHS Blood test didn’t test for vitamin levels but I take biotin, b12, vit D, & magnesium. As well as HRT.

Hmmm... that's a hefty dose of T3 when only 4 months ago you were on 150mcg Levo only, your fT3 results weren't that bad at 5 something then so I'd have thought you have missed your sweet spot, I wouldn't be surprised if just a small amount of T3 (5mcg) added to maybe 125mcg of T4 would have done the trick

How long after the last dose is this result?

[Bright-eyes in reply to TiggerMe]

Thanks for your response Tigger. Yes I was on 150 Levo and T3 12.5 mcg but was still very fatigued come the afternoon needing to sleep as exhausted. Which is why I started tweeking my does. I guess in my mind I’m thinking of eventually trying T3 only. I took last Levo and T3 24hrs before blood test

Ok, so looks like you've missed your sweet spot, even when you find it it can take months to gradually improve and recover, over replacing makes you feel equally awful.

Were your previous result done with the same 24 hour gap? If so it would suggest 15mcg T3 would be more than enough to increase and stick with for at least 8 week

Leaving a 24 hour gap between your dosing to test gives a false reading, lower than it would be on a 'normal' day, ideally always test under the same conditions to make results comparable

Previous results on 150mcg T4 and 12.5mcg T3

fT4 a bit high but dropping 50mcg would be too much and adding 25mcg T3 way too much

If your last dose of T3 was 24 hours before the blood draw then you have a false 'low' FT3 - it is actually a lot higher than that. The recommended gap is 8 to 12 hours.

Ok.. I didn’t know that Thankyou and will keep this in mind for future test.

[greygoose in reply to Bright-eyes]

What you need to have in mind right now is that you are probably over-medicated and that can be as bad as being under-medicated.

Do you also have an FT4 result?

Your FT3 is a false low at 91% of range so likely in reality over range. Suggest you drop T3 by 5mcgs and retest in 6-8 weeks.

In future split T3 day before test and take last portion 8-12hrs before the test.

Most people need a B complex that will include folate.

What was your last ferritin result and have you had an iron panel?

didn’t test for vitamin levels but I take biotin, b12, vit D, & magnesium. As well as HRT.

Did you stop biotin 5-7 days before test ?

You need to test folate, B12, vitamin D and ferritin at least annually

IMPORTANT......If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 5-7 days before ALL BLOOD TESTS , as biotin can falsely affect test results

In week before blood test, when you stop vitamin B complex, you might want to consider taking a separate folate supplement (eg Jarrow methyl folate 400mcg) and continue separate B12

Free T4 (fT4) 11.3 pmol/L (7.9 - 16) 

Ft4 only 42.0% through range

So as well as Ft3 being too high

Likely Ft4 is possibly too low

You may eventually need a SMALL increase in Levo - eg 112.5mcg 4 days a week and 100mcg 3 days
