Abstract
Normal estradiol and progesterone reference ranges in NaProTECHNOLOGY are derived from fertile, ovulatory cycles with confirmed CrMS Peak days and sonographic ovulation, with blood sampling timed to Peak-anchored days (pre-ovulatory P-days for estradiol, P+3 through P+11 for luteal hormones) rather than to calendar cycle days. These day-specific normative values allow detection of subtle deficiencies -- such as a blunted progesterone rise at P+5 or inadequate pre-ovulatory estradiol -- that are clinically actionable for diagnosing follicular and luteal phase disorders but are invisible to standard mid-luteal or phase-independent reference intervals.
