All fields are required unless noted optional. The PSA velocity measures the rate at which PSA values change over a period of time, with any change greater than 0.75 ng/mL per mL per year being of concern. Even when the total PSA value isn't higher than 4, a high PSA velocity (an increase greater than 0.75 ng/mL in one year) suggests that cancer may be present and a biopsy should be considered. This tool can be used to calculate the rate of rise of PSA, expressed as the velocity in nanograms/mL/year, or the PSA doubling time, in months or years. With PSA velocity, what matters is a significant change over time, and for this to be accurate, you need to have multiple PSA measurements taken in the same laboratory, because PSA measurements can vary slightly from lab to lab. Rather, it is the change in PSA levels over time. JAMA.
