The researchers write that “the historic cut point of 4 ng/mL, often used as a threshold for further evaluation, is likely far too high a threshold for this population.”
Nik-Ahd noted, “clinicians should interpret PSA values in transgender women on estrogen with extreme caution. In this population, normal might actually not be normal, and a value that is considered normal might be very abnormal for somebody who is on estrogen. If you're unsure of whether a PSA value is appropriate for a transgender woman on estrogen, refer that patient to a urologist so they can undergo further evaluation.”
