Estradiol levels are minimal and according to most laboratories range from 20 to 80 pg/mL during the early to mid follicular phase (or the first week of the menstrual cycle, also known as menses). [ 63 ] [ 64 ] Levels of estradiol gradually increase during this time and through the mid to late follicular phase (or the second week of the ...
100–200 pg/mL <55 ng/dL [4] Callen-Lorde: United States "Some guidelines recommend checking estradiol and testosterone levels at baseline and throughout the monitoring of estrogen therapy. We have not found a clinical use for routine hormone levels that justifies the expense.
During pregnancy, levels of estradiol increase to very high concentrations that are as much as 100-fold normal levels. [ 138 ] [ 139 ] [ 140 ] In late pregnancy, the body produces and secretes approximately 100 mg of estrogens, including estradiol, estrone , and estriol , per day. [ 138 ]

The levels of hCG in the body increase rapidly in the first few weeks of pregnancy, doubling every 48–72 hours. [7] The highest level of hCG is reached in week 10 or week 11, later the levels of hCG can be used to estimate the age of the fetus and monitor the progress of the pregnancy. [6]
