PHI (prostate health index) test

Dr Geoff Coughlin may discuss having a prostate health index blood test performed.

This is a promising new blood test based on prostate-specific antigen (PSA), which has recently been approved in the United States, Europe and Australia. PHI is a mathematical formula that combines total PSA, free PSA and [-2] proPSA.

Numerous international studies have consistently shown that PHI outperforms its individual components for the prediction of overall and high-grade prostate cancer on biopsy. PHI also predicts the likelihood of progression during active surveillance, providing another non-invasive modality to potentially select and monitor this patient population.
