Women with irregular cycles can test serum hormones any day of their menstrual cycle.
Reference ranges will be provided for estradiol, progesterone, FSH, and LH for the follicular, ovulatory, and luteal phases so that you may assess which phase the results correlate with and whether further workup with Saliva Hormones or Urinary Hormones is indicated.
Please see attached Serum Hormones Sample Report and Serum, Saliva, & Urine Hormones Comparison resources for reference.
