Why would Endo order this test?
I just recieved my labwork in the mail that my Endo ordered. I noticed a new test that I've never seen listed on the paper.
It is T4, Free, Direct Dialysis. The results say pending so I hope to have the results soon.
My question is..... What is the purpose of this test? What's this test going to show that Free T4 does not?
Thank you for any feedback that you can offer. Thanks so much!!
