Reference Range
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)
