Prostate Health Index (phi)

An FDA approved, CE marked blood test analysis to be used as an aid in distinguishing prostate cancer from benign prostatic conditions1

phi is a proprietary calculation developed by Beckman Coulter Inc. that uses a combination of three blood tests to produce a "phi score." This phi score provides more information about what elevated PSA levels might mean and the probability of finding prostate cancer on biopsy.*
