How to read this marker
Often used when total PSA is in an indeterminate zone. Use the performing-lab risk table.
The wider testing context
Age, prostate anatomy, symptoms, medications, infection, procedures, and testosterone therapy can materially affect interpretation.
Using this reference
This is the approved adult, nonpregnant baseline unless the rule explicitly states otherwise. Keep the performing laboratory’s reference interval separate from this Purser Wellness rule. Match units and review the specimen, method, timing, medicines and relevant clinical context before interpreting a result. These pages do not calculate a personal high/low status or prescribe treatment.
