Guidance® Pre Prostate Biopsy Rectal Swab (GPPBRS) Test

The Guidance® Pre Prostate Biopsy Rectal Swab (GPPBRS) test identifies antimicrobials that may be used prophylactically by using our patented Pooled-Antimicrobial Susceptibility Testing (P-AST™) technology to determine the presence or absence of resistance genes. When an appropriate antimicrobial is used before and after the prostate biopsy procedure, the risk of infection is reduced.

The GPPBRS test is the ONLY test that combines PCR & patented Pooled Antibiotic Susceptibility Testing (P-AST™) technology so the Urologist is able to precisely identify and prescribe antibiotics PRIOR to the prostate biopsy procedure thereby significantly reducing the chances of sepsis for the patient.

Sample Methods

GPPBRS Test VS. Culture Test

Faster Turnaround Time
GPPBRS test will provide results in 24 – 48 hours while culture test takes more than 72 hours.

Easy-To-Interpret Lab Report
GPPBRS lab report is based on the concept of our flagship Guidance® UTI lab report.

Tests for Mutualism
GPPBRS utilizes the patented Pooled Antibiotic Susceptibility Testing (P-AST™) to test for mutualism while culture cannot.

Tests for Resistance Genes
GPPBRS tests for 8 resistance genes while culture tests for 0.
