What is the Prostate Health Index (phi)?

The Prostate Health Index is three things: a simple blood test to improve early detection of prostate cancer, a tool to reduce negative biopsies and provide more confidence in your biopsy decisions, and is used as a recommendation by the National Comprehensive Cancer Network (NCCN) Guidelines for PCa Early Detection prior to transrectal ultrasound (TRUS) guided biopsies.

The Prostate Health Index (phi) comprises three tests in combination:

PSA
free PSA
p2PSA

The new p2PSA assay specifically measures [-2]proPSA. The [-2]proPSA biomarker is an isoform of free PSA that was identified as the most prostate cancer-specific form found in tumor extracts.1 The PSA, free PSA and p2PSA results are combined in the Access instrument to calculate a probability of prostate cancer.
