Primary source
Benson MC et al. Prostate specific antigen density: a means of distinguishing benign prostatic hypertrophy and prostate cancer. J Urol. PMID: 1371554. Volume uses the prolate ellipsoid, length × width × height × π/6, and PSA density is PSA divided by that volume in mL. A density of 0.15 or greater was the published decision threshold; values are shown to 0.1 ng/mL per mL. (1992)
