Test Details
Methodology
Enzyme-linked immunoassay (ELISA)
Result Turnaround Time
1 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Evaluate for ovarian estrogen producing tumor in the premenarcheal and postmenopausal female; evaluate estrogen excess in males. Estrogen analysis may be helpful in establishing time of ovulation and optimal time for conception. Serial samples must be collected over several days to evaluate baseline and peak total estrogen levels.
