This test begins with the analysis of prostate-specific antigen (PSA). If the PSA is between 2.0 and 10.0 ng/mL, then the reflex test (PHI13) will be performed.

If the initial PSA is between 2.0 and 10.0 ng/mL, then free PSA and [-2]ProPSA will be reported.

If the initial PSA is between 4.0 and 10.0 ng/mL, then the percent free PSA and prostate health index (phi) will be calculated and reported.

If the initial PSA is between 2.0 and 4.0 ng/mL, then the percent free PSA and prostate health index (phi) will not be calculated or reported.

  

Aids in distinguishing prostate cancer from benign prostate conditions in men with total prostate-specific antigen (PSA) concentrations in the 4 to 10 ng/mL range and digital rectal examination (DRE) findings that are not suspicious for cancer

  
  • Specimens for testing should be drawn prior to prostate manipulations such as digital rectal examination (DRE), prostatic massage, transrectal ultrasound (TRUS), and prostatic biopsy.
  • Specimens should not be collected from patients receiving therapy with high biotin (vitamin B7) doses (ie, >5 mg/day) until at least 8 hours following the last biotin administration.
