I’ve been anxiously waiting for all our data to roll in from an exciting study, and we’re now ready to share it. What we did shows a very distinct advantage to our model of testing with respect to estrogen testing.

Here is what we did in our study:
  • Collected serum, saliva and dried urine samples from a group of women throughout their entire cycle (we included one first-trimester pregnancy case as well)
  • Collected serum, saliva and dried urine samples from a group of postmenopausal women (with no history of HRT)
  • Serum samples were tested for estradiol (E2) and progesterone (Pg) by the Reproductive Endocrinology Dept at U. of Southern California (USC)
  • Saliva samples were mixed, split and sent to 7 different saliva labs (one lab’s data showed no cycle of E2 or Pg in contrast to all other data, so their data was excluded)
  • Dried urine samples were tested at our facility by GC-MS/MS for estrogen and progesterone metabolites
  • Urine was also tested for LH for premenopausal women to more accurately identify the ovulatory surge of LH and E2
