Hi, all,

I plan to have my sex hormone panel tested, including 6 hormones,
Estrogen (E2)
FSH
LH
PRL
Testosterone
Progesterone

However, I received contradictory information from two endo doctors. One told me to have them tested on the 3rd day OF(within) the mentrual cycle, the other said I should be tested on the 3rd day AFTER the menstrual cycle. Also I saw on the internet that some people tested the first way, some other tested the second way. I am really confused!!

I googled for follicular phase, it lasts for about 13 days when the mentrual cycle began. So both times are included in this phase, and the lab references are in this phase, too. But that information doesn't give a clear clue/hint on the best time for tests.

Last time I have 3 of them tested, but tested on the 3rd day OF(within) the mentrual cycle, found the E2 is a little low. But I heard that it will be up after the menstrual cycle is finished.

E2 22.3 (11-165)
Progesterone 1.08 (0.15-1.4)
Testosterone 33.10 (14-76)

Anyone has wise points or experiences on it? Should I ask a 3rd,4th...Nth doctor to confirm? Thanks.
