Our polymerase chain reaction (PCR) technology is the fastest and most accurate test for a urinary tract infection (UTI)

Although widely used, culture-based methods for the detection of pathogens involved in urinary tract infections (UTIs) lack sensitivity, are subjective, take a long time, and have been shown to miss a significant percentage of positive cases. Current culture plating methods can typically take anywhere from 18 to 30 hours—even longer with subsequent antimicrobial sensitivity analysis.

A New Molecular Solution for UTI Testing

GRI’s new real-time polymerase chain reaction (PCR) technology enables rapid urinary tract microbiota (UTM) detection in under five hours—allowing for flexible content, and optimized for multiple throughputs. This technology is the first commercially available molecular solution for UTI pathogen detection that labs can implement themselves.

Verification data demonstrates that our PCR-based solution is over 25% more accurate when compared to traditional culture-based methods of detection.

State-of-the-Art PCR Technology

GRI Labs’ system takes urinary tract infection (UTI) testing to the next level. Designed for maximum throughput, flexibility, and scalability, the technology sets the new standard for what a real-time PCR instrument should be. Combining flexible throughput capabilities with a streamlined workflow, intuitive software, and a state-of-the-art industrial design, these instruments support targeted discovery through confirmation and screening, and everything in between.

Increased Sensitivity and Specificity for Urinary Tract Infections

Real-time PCR testing for UTI can detect slow-growing, difficult-to-cultivate microorganisms, making it ideal for when culture methods are inadequate, ambiguous, time-consuming, difficult, and costly.

We are able to detect the following bacterial and fungal organisms:


Acinetobacter baumannii
Citrobacter freundii
Enterobacter aerogenes
Enterobacter cloacae
Enterococcus faecalis
Enterococcus faecium
Escherichia coli
Klebsiella oxytoca

Klebsiella pneumoniae
Morganella morganii
Proteus mirabilis
Proteus vulgaris
Providencia stuartii
Pseudomonas aeruginosa
Staphylococcus saprophyticus
Streptococcus agalactiae


Candida albicans



Color-Coded, Patient Friendly Reports

GRI doesn’t just provide accurate testing, but we present our results in an easy-to-read, patient-friendly format. Far removed from the cryptic reports of the past, our color-coded reports can help you to have a more productive discussion with your patients about their health.
