I've just had this done (AMH test). My GP was happy to order the test for me and was going to cost $120ish but because I was going back for another IVF cycle anyway, got it done through the IVF clinic and only cost me $68, so is cheaper to get it done through IVF clinics but GPs can do it for you. My result was as expected after trying for many years and having unsuccessful attempts at IVF for a second baby. I'm glad I got it done as I think I needed it written in ink that my time has pretty much run out. Normal I'm told is around a score of 10 or above. I was 3.6 and am only 37 but is likely due to my many years of endometriosis. Who knows, but I'm still giving it a last shot or 2.

Oh - and I should add in that the test takes approx. 2 weeks before you get results back and its recommended you do the test 2 months after stopping the pill as it can affect the results.
