Ordering Recommendation

Use this mass spectrometry test to measure a wide range of testosterone concentrations. Most useful when low concentrations are expected, regardless of the patient’s sex assigned at birth. Use to monitor testosterone-suppressing hormone therapies (eg, antiandrogens or estrogens). Free or bioavailable testosterone measurements may provide supportive information.

To compare this test to other testosterone tests, refer to the ARUP Testosterone Tests Comparison table.
