Sadly, the sensitive test is almost impossible to find outside of the United States. We hear from members living elsewhere who look for it, high and low, with no success. Anecdotal accounts of it being offered in Germany have appeared recently, but as of yet no commercial lab or hospital has been identified here at EM.
Its a tangled story. Doctors resisted measuring estradiol in men on TRT for years, that's beginning to change. However, now the battle is over which testing methodology ought to be used. The verdict is clear, the only appropriate and reliable test is the sensitive (LC, MS/MS) process, but doctors - and labs - are dragging their heels on this as well. So many battles in TRT take far too long to win.
Your doctor could have blood drawn and expressed to a lab in the US. I know of one fellow in Ireland who did just that. But you can imagine how expensive that can be.
