PSA Free (Prostate Cancer)
Free PSA measures the portion of prostate-specific antigen not bound to plasma proteins and is used alongside total PSA to refine prostate cancer risk. A higher percentage of free PSA suggests benign prostate enlargement, while a lower percentage raises concern for cancer. It helps reduce unnecessary biopsies when total PSA is only modestly elevated.
