The EPI Test

the epi test

The ExoDx Prostate® (IntelliScore) – EPI – is a simple, non-invasive urine test that measures three important genomic RNA bio-markers which can be used by you and your physician in discussing your need for a prostate biopsy. This test helps you and your physician in making an informed prostate biopsy decision. 

This is a test designed for use in men 50 years and over with a PSA between 2–10 ng/ml who are being considered for initial biopsy.

How EPI Works

It starts with a simple urine sample

All you need is an order from your physician and a special urine collection device provided to your doctors office by Exosome Dx. No blood draw or DRE required.

We analyze the exosomes in your urine
