Experts in PCR laboratory testing

PCR has become a familiar term due to Covid-19 testing. Yet the benefits of PCR technology are available for a broader range of respiratory tests, including GI and respiratory infections, STDs, UTIs, and wound care*.  

As compared to traditional culture testing methods, PCR testing is a faster and more reliable way to diagnose and identify the best treatment. Molecular PCR testing works by amplifying or copying small segments of DNA for analysis. The results of this analysis include Antimicrobial Resistance to help determine if a medication may be effective.

GRI Labs’ system for real-time PCR testing is designed for maximum throughput, flexibility, and scalability.
