Thanks guys.  I will keep up the Vitamin D and get it retested.  And just to make sure I have this correct, I would like to see if I can summarize what all I need to do on this blood draw on the 25th. 


As of this morning(April 19th) I took my 30th pill of Synthroid.  Should I stop taking it as of now, or continue its use and get tested on the 25th?


What are all the additional test I need to ask for.  I know the Reverse T3 is one of them.  I know I want my vitamin D tested again?  DHEA?  Sensitive on the Estrogen, correct? 


If someone could just please summarize what I need to ask for additionaly on top of what was tested originally.


Also...my wife is going to go with me and get her blood drawn.  Not necessarily to start any hormones, but that she wants to see what is going on with here body.  Are there any specific test she should ask for?

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
