Estrogens, Fractionated, by Mass Spectrometry
Use to evaluate estrogen status in children, cisgender males, and postmenopausal cisgender females. Most useful when low estrogen concentrations are expected, regardless of the patient’s sex assigned at birth.
To compare this test to other estrogen tests, refer to the ARUP Estrogen Tests Comparison table.
