DRG Laboratory provides the latest cutting edge, state-of-the-art PCR based diagnostic testing available to medical practitioners. Our testing is so sensitive and exquisitely specific that it can detect a single copy of genomic DNA. We test for over two dozen bacteria, parasites, fungi, and health risk markers. When you order this life altering test you will receive a complete, easy to use collection kit that you return, postage-paid, 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 a few business days.

PCR: Polymerese chain reaction – it’s DNA

“PCR is the best developed and most widely used nucleic acid amplification strategy. These techniques have sensitivity unparalleled in laboratory medicine; they have created new opportunities for the clinical laboratory to have an effect on patient care and have become the new “gold standards” for laboratory diagnosis of several infectious diseases.”

Manual of Clinical Microbiology, 8th Edition, Vol. 1, page 235, 2003.

DNA doesn’t lie…

gel-readers-for-genetic-testingThe clinical microbiology laboratory is transitioning into the molecular age. From pathogens and antibiotic resistance identification to screening tests, molecular diagnostics are playing an increasingly important role in diagnosing infections and improving patient outcomes. Knowledge of the presence of a drug resistance gene is significant when considering a patient’s treatment for a pathogenic infection.

Tomorrow’s Medicine Today

Many infectious agents missed by routine cultures, serological assays and Southern blot hybridizations can be detected by PCR. Therefore, PCR-based tests are best suited for the clinical and epidemiological investigation of pathogenic bacteria and viruses.pcr-bacteria-clipart The limitations of culturing are: low sensitivities, inability to detect non-cultivatable bacteria, time-consuming aspects and low levels of reproducibility. pcr-virus-clipart Microscopy for parasites requires up to 3 samples and a high number of cells, 1000 to 5000 per gram for diagnosis. Even with the advent of antigen detection systems, there has long been uncertainty in diagnosis when no bacteria or parasites are found. And virus detection is not routinely available by conventional labs.pcr-fungus-clipart In contrast, PCR based assays require only 1 to 5 cells per gram of stool, are not limited by growth requirements, are very reproducable and have nearly 100% sensitivity and specificity. Making PCR the most sensitive method available.
