PSA density
Abbreviations: PSAD
Definition: The relationship of the PSA level to the size and weight (volume) of the prostate. PSA value is divided by the prostate size (measured by ultrasound). It is used because an elevated PSA might not arouse suspicion in a man with a very enlarged prostate. The use of PSA density to interpret PSA results is controversial because prostate cancer might be overlooked in a man with an enlarged prostate.
