Re: new LABS - need help figuring Ft3/rt3 ratio - i'm the one w/ weird sxs, val!

[Guest guest]

I think I need to clarify that the FT3 was measured in pg/dl and the RT3 was

measured in pg/ml.

(I did the labs about 30 mins. apart, fasting, in the morning. but had to do the

RT3 at LabCorp and did the others at Quest. It was because I used my doc's

discount for some labs and had to use econolab for the Rt3 as my doc's office

deal for some reason doesn't inclue rt3 testing! WAY more info than you

needed!)

I'm metric-challenged, along with everything else. I just keep trying to do the

math by myself and no number is making sense.

Thanks much!

25mcg Cytomel. My Rt3 dominance was still able to clear. (Though don't know

what the ratio is now. My brain fog won't let me figure it out!)

my horrific brain fog was much worse on 2 grains of NT, which makes sense as my

ratio went from 17 on 1 grain of NT to 11 on 2 grains. It's like my body needs

the increased dose, but can't tolerate it. And, I also can't tolerate the

increase in cytomel!!!

didn't budge my Ft4 after 6 weeks, and my TSH DROPPED.) Again, not sure what my

ft3/rt3 ratio is.

Hi Carol

I think your ratio is

2280/124 = 18.4

Thanks very much, Josie! Maybe Nick or Val can weigh in, if you're not sure!

(though it makes sense, now that I look at it.)

I'd very much like to get mods (or those who have ideas) thoughts on what might

be going on with the lab trends. I could really use some help.

Thanks!

Thoughts are you are not on enough and are not matching the HC and T3

doses together.

At that dose level of T3 your own thyroid is still producing T4 and

hence the levels vary when you take more of less T3.

My gut feeling is you need to increase T3 AND HC at the same time.

The extra T3 drops your temperature because it uses up HC and you

don't have any reserves.

I would try adding more T3 and increase the HC at the same time,

spread the T3 out through the day.

If temperature drops on taking T3 it's a sign more HC is needed.
