Blood vs Saliva Testing for FT3

[Guest guest]

HI Val....I'm a little confused about saliva vs. blood testing for

thyroid.

If a blood test showed very high t3...we assume it's not getting into

the cells, right? Then, what would the saliva test show....low t3?

If my blood tests came back high (on Cytomel only) should I bother

getting a saliva test done then? Is it a given that there will be low

thyroid at the cellular level?

And....is there ever the scenario where blood will show high, but

saliva will show normal?

It's kind of confusing for me....please explain and thanks!
