I have had mine tested and it was in the very low range <0.3. My gyne, due to my age of 42 was reluctant to chalk all my symptoms to perimenopause, and then results came back and I was told likely full menopause in the next couple years. Very few follicles left, therefore all most done, I was also told that this is very reliable in regards to nothing really affecting results, even if currently taking hormones while on it. So, there you have it, I do not think a lot of places test for it, however I was fairly insistent to her that my symptoms were hormone related and she did reluctantly check everything. The whole thing is incredibly frustrating, but keep advocating for yourself!
