Estradiol is the type of estrogen that is normally measured with testing, and a normal range is 30-400 pg/mL for premenopausal women (depending on where you are in your menstrual cycle) and 0-30 pg/mL for postmenopausal women. Levels lower than 20 pg/mL may cause hormonal symptoms such as hot flashes.
