What we measure: the Prostate Health Index (PHI)


PHI combines multiple prostate-related biomarkers into a single score to help stratify the likelihood of clinically significant prostate cancer. It’s intended to be used as an aid—alongside clinical evaluation—when considering whether a biopsy is appropriate.
