PSA velocity

(redirected from PSAV)
Also found in: Acronyms.

PSA velocity

a measure of the rapidity of change in a person's PSA level.

PSA velocity

Prostate-specific antigen velocity. A triggering factor for assessing PSA levels in the decision to refer a patient for a prostate biopsy. A PSA velocity of greater than 75 ng/mL/year should trigger a biopsy referral.

Cons
Requires PSA measurements over many years and does not factor in variability of the assay methodologies.

PSA ve·loc·i·ty

(vĕ-los'i-tē)
A measure of the rapidity of change in a person's level of prostate-specific antigen.

PSA velocity

The rate of rise in the level of prostate-specific antigen. An increase in the level by more than 2.0 nanograms per millilitre in the year prior to the diagnosis of prostate cancer suggests a relatively high risk of death from the disease in spite of radical prostatectomy.
