Re: Ok my friends...difference between tests, my lab sheet doesnt have t3 Free
The "Free" means these are the free hormones available for use by the body. Once the hormones become bound to proteins the body cannot use them.
All the others (not the Free's) include calculations that include the protein bound hormones. So not all of those values are useable by the body.
That is why the free's are important. It shows exactly what your body has to work with.
I don't know specifically the differences between each exact test. Only that they all include the protein bound counts. Only the free's do not count the protein bound hormones.
I think that's how it goes anyway. Somebody correct me if I am wrong.
