Prostate Health Index (phi): Beckman Coulter

phi is exclusive to Beckman Coulter and therefore must be run on a Beckman Coulter immunoassay analyzer. If your laboratory includes a Beckman Coulter analyzer, it's easy to get the laboratory set up to run these tests. 

If unsure whether or not your laboratory has a Beckman Coulter analyzer, or you would like information about how to get phi implemented in your laboratory, please contact them at 1-800-526-3821. 

Interested in trying phi before you bring in house?

If you do not have a Beckman Coulter analyzer to run phi, consider sending out to ACCU Reference Medical Lab or Innovative Diagnostic Laboratory. 


ACCU Reference can be reached via email at or via phone at 1-800-766-8378

Innovative Diagnostic Laboratory is able to provide customized order forms as well as testing kits with included postage. They can be reached via phone at 1-855-420-7140
