PCR Testing- Invasive and Non-Invasive

PCR (which stands for Polymerase Chain Reaction) is a biochemical technique performed in laboratories and is the "Gold Standard" for identifying organisms. There are many medical, legal and research uses for PCR, including virus and bacteria identification, forensic matching and diagnosing disease (such as genetic disorders).


Invasive Testing:

DRG Laboratory’s Medical Director is a seasoned expert in Pathology and the Associate Medical Director has a specialty in Parasitology. Because of the tedious nature of culturing and the inaccuracy of chemical analysis, the group developed means of diagnosing Bacteria, Viruses and Parasites utilizing State-of-the-Art PCR technology. Not content to stop there, the team went further and developed their methodology to quantify as many of the organisms as practical to provide the physician with hard evidence of the level of infection. To aid the physicians in their efforts to effectively treat their patients, DRG went one step further and engineered “Patient Specific Antibiotic Resistance” to 5 entire classes of drugs. This is highly complex science and to our knowledge, DRG Laboratory is the only facility in the United States offering this level of information and support to the physicians. DRG continues their efforts in Research and Development. Additional assays for Cancer markers are being developed.
