Children*
1-14 days: Estradiol levels in newborns are very elevated at birth
but will fall to prepubertal levels within a few days.
Males
Tanner Stages Mean Age Reference Range
Stage I#: 7.1 Undetectable-13 pg/mL
(>14 days and prepubertal)
Stage II: 12.1 Undetectable-16 pg/mL
Stage III: 13.6 Undetectable-26 pg/mL
Stage IV: 15.1 Undetectable-38 pg/mL
Stage V: 18 10-40 pg/mL
#Puberty onset (transition from Tanner stage I to Tanner stage II) occurs
for boys at a median age of 11.5 (+/- 2) years. For boys, there is no
proven relationship between puberty onset and body weight
or ethnic origin. Progression through Tanner stages is variable.
Tanner stage V (adult) should be reached by age 18.
Females
Tanner Stages Mean Age Reference Range
Stage I#: 7.1 Undetectable-20 pg/mL
(>14 days and prepubertal)
Stage II: 10.5 Undetectable-24 pg/mL
Stage III: 11.6 Undetectable-60 pg/mL
Stage IV: 12.3 15-85 pg/mL
Stage V: 14.5 15-350 pg/mL**
#Puberty onset (transition from Tanner stage I to Tanner stage II) occurs
for girls at a median age of 10.5 (+/- 2) years. There is evidence that it
may occur up to 1 year earlier in obese girls and in African-American
girls. Progression through Tanner stages is variable. Tanner stage V
(adult) should be reached by age 18.
*The reference ranges for children are based on the published
literature (1,2), cross-correlation of our assay with assays used to
generate the literature data and on our data for young adults.
Adults
Males 10-40 pg/mL
Females
Premenopausal: 15-350 pg/mL**
Postmenopausal: <10 pg/mL
**E2 levels vary widely through the menstrual cycle.
Conversion factor:
E2: pg/mL x 3.676 = pmol/L (molecular wt = 272)
