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).
