About DRG Lab


DRG Laboratory is a leading edge company focused on the most sensitive DNA laboratory diagnostic testing.  Utilizing the most advanced technology available and having been in operation since 2012, DRG is the premier PCR diagnostics testing laboratory in the country. We test for multiple pathogens, parasites, and viruses.  DRG utilizes GI inflammatory health markers that provide detailed information about possible inflammation that could occur in the digestive system.

Our molecular testing is so sensitive and exquisitely specific that it can detect a single copy of genomic DNA.  When you order a DRG test you will receive a complete, easy to use collection kit that you return, postage-paid (US only), with your specimen. We process your specimen as soon as it is received in our state-of-the-art facility and provide your test results directly to your physician usually within three to four business days.

With advanced PCR technologies, it is possible to measure hundreds of organisms, literally taking billions of copies of an individual’s DNA.  DRG BILLS all valid US private insurance companies, as well as  Medicare, Medicaid, TRICARE and Railroad. If you would like to receive additional information about our testing, please contact customerservice@drglab.com, or call (678)580-0613 – option 2.
