Estradiol (Adult Males, Children, Postmenopausal Females, or Individuals on Estrogen-Suppressing Hormone Therapy)
Ordering Recommendation
Use this mass spectrometry test to measure a wide range of estradiol concentrations. Most useful when low estradiol concentrations are expected, regardless of the patient’s sex assigned at birth. Use to monitor estradiol in individuals on estrogen-suppressing hormone therapies (eg, aromatase inhibitors or testosterone).
To compare this test to other estrogen tests, refer to the ARUP Estrogen Tests Comparison table.
