Use:
This test is used to evaluate ovarian estrogen producing tumor in the pre-menarcheal and postmenopausal females, as well as 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.
Methodology:
Radioimmunoassay (RIA)
