DRG Laboratory is a leading edge company focused on the growing field of DNA based laboratory diagnostics and has been in business since 2012. Utilizing the latest technologies, DRG is the premier PCR Diagnostics Testing Company in the USA and is the ONLY one with Q-PAR™. Our Technology advances provide each practitioner with Quantitative results and Phenotypic Antibiotic Resistance (Q-PAR™) providing the complete picture for the first time.

This dramatic advantage allows the patient to have their treatment protocol designed to their specific bacteriological makeup.  Given that Antibiotic Resistance has been labeled “A greater threat to this country than Terrorism”; physicians all across the country will now be able to aid in the fight against Bacteria developing resistance to all of our known Antibiotic Drugs while providing better treatment options to their patients.

With the advent of DNA techniques it is now possible to measure hundreds of organisms, including Bacteria, Parasites and Fungi at one time with extremely high accuracy. Our assays assist physicians in the diagnoses of GI complaints in a way never before available. This level of diagnostic ability is not available other laboratories.  It truly is “cutting edge, State-of-the-Art” testing.  And all of the Major Insurances cover this Technology.

Dr. Antoinette Gaston
Laboratory Director


Lab Director - Dr. Antoinette GastonA devoted scientist at an early age; Dr. Antoinette Gaston began her career as a Researching Scientist in the late 1990’s. She attended Wright State University’s School of Medicine (now Boonshoft School of Medicine) in Dayton Ohio, upon completion of her B.S. in Biology from the University of Akron.  While at Wright State, she developed a passion for incorporating laboratory and diagnostic testing in a manner that can be used to assist in predictive care for patients.   While at Wright State, Dr. Gaston began to search for the best path to further her knowledge in the biological sciences.  Her search led her to Tennessee State University to obtain her graduate degree, M.S., and Ph.D. in Biological Sciences with a concentration in Molecular Biology/Microbiology.

While at Tennessee State, Dr. Gaston had the privilege to attend school on fellowship awards from NIH, NASA, and the Department of Agriculture.  This enabled her to perform research to genomically and phenotypically identify new strains of Chromobacterium violaceum. This laid the foundation of utilizing the extracted violacein as an anti-tumor, anti-microbial, and anti-fungal agent.   The studies she performed at Tennessee State University provided her with the molecular and toxicology skills to obtain employment with Aegis Sciences Corporation, Esoterix Genetic Laboratories, and Orchid Cellmark.  In 2010, Dr. Gaston along with a colleague, started her first laboratory services with direct to consumer business; Lab Tests Etc. Lab Tests Etc. empowered the public with tool to manage their own healthcare.

In 2014, Dr. Gaston and her colleagues sold their lab venture, and she moved to the Atlanta metro area and began directing laboratories and providing consulting services.  As a laboratory consultant, Dr. Gaston helped physicians and business investors design and implement clinical laboratory testing services.   This enabled the physician to provide onsite clinical laboratory testing for their patients and provided business investors with an expansion of their portfolio that enriched the lives of patients.   Her passion to develop testing services that enrich the quality of life of patients is what led Dr. Gaston to DRG Laboratory as their Laboratory Director.

After learning DRG’s mission, Dr. Gaston came to the laboratory to assist in the expansion of the laboratory testing services, and to provide directorship of the laboratory staff to accomplish the lab’s mission.  DRG Laboratory’s owners, Karen and Charles Stout, are committed in providing practitioners with testing services that enable them to effectively treat their patient’s gastrointestinal conditions.  Their focus of helping the provider direct their treatment plan based upon the identification of the pathogens present in the GI system and the virulence of those pathogens removes the “practice” from medicine.
