PSA Velocity (PSAV) Calculator

Calculate PSA velocity (PSAV) as the rate of change in PSA over time. A PSAV >0.75 ng/mL/year is suspicious for prostate cancer even when absolute PSA is in the normal range. Requires at least 2 PSA measurements over 18 months.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
