Measuring hormones at peak estrogen/progesterone and baseline testosterone, plus a second test on day two of bleeding, is sufficient to obtain over 75% of relevant data.

“And for women, the trick is going to be when you get your blood taken with respect to your hormone cycle, your ovulatory cycle, and to try to make that at least consistent from test to test, not necessarily having to go in both during the follicular and the luteal phase of your cycle, but always going in during mid-follicular or mid-luteal, and that can be challenging to do perhaps.”

“and if she can add a second blood test at a different phase of the menstrual cycle where would you place that second test day two of the menstrual cycle second day of bleeding to get a really good indication of what your true estrogen level is at Baseline”

“if she measures her hormones at those two times within the cycle do you think that's sufficient to um get 75% plus of the relevant data yeah definitely”

“and if she can add a second blood test at a different phase of the menstrual cycle where would you place that second test day two of the menstrual cycle second day of bleeding to get a really good indication of what your true estrogen level is at Baseline”

“you get a good indication of estrogen progesterone Peak testosterone doesn't fluctuate as much as those two so you're going to get a good idea what Baseline testosterone is”

“if I'm limited to say that then I would say 5 to seven days before her next period starts so mid ludal because then you get a good indication of estrogen progesterone Peak testosterone doesn't fluctuate as much as those two so you're going to get a good idea what Baseline testosterone is”

“so yeah I would say if you could only do it at one point in time that would be the time to do it”

“any point in time when you get a blood draw on a woman and you are looking at FSH LH estradiol and progesterone you have to sort of know where you are”
