IDEXX Reference Laboratories Introduces First Quantitative Real-time PCR Test for Canine Distemper Virus

    Canine Distemper Virus (CDV) Quant RealPCR™ Test differentiates between naturally infected and vaccinated dogs

    WESTBROOK, Maine, October 11, 2011 - IDEXX Reference Laboratories announces the availability of the Canine Distemper Virus (CDV) Quant RealPCR™ Test, a revolutionary new canine distemper virus (CDV) test that differentiates infected dogs from those vaccinated for the disease. The test allows veterinarians to make a more accurate diagnosis of dogs with clinical signs of respiratory illness. The new test has been incorporated into IDEXX Reference Laboratories' existing canine respiratory disease panels at no additional cost. Results are available in just 1-3 days.

    Clinical signs of illness usually develop in dogs, particularly puppies and adolescents, within days of adoption from kennels or shelters where they would have been recently vaccinated. Until now, this has made it challenging to interpret positive qualitative test results. The CDV Quant RealPCR Test provides a quantitative measure of the CDV viral load, which is typically exponentially higher during infection than what would be detected because of recent vaccination.

    Christian Leutenegger, DrVetMed, PhD, FVH, Regional Head of Molecular Diagnostics, developed the new test in collaboration with veterinarians from the University of Florida. "IDEXX RealPCR tests advance medical care by delivering unprecedented accuracy," said Dr. Leutenegger. "Innovative real-time PCR technology indicates not only the presence but also the quantity of the virus. We run this test in a state-of-the-art facility with automated viral load calculation, using seven quality controls. Veterinarians can be confident in the results and in their diagnosis of CDV in patients."

    A stand-alone test is also available for quantitative distemper virus information from swabs collected from respiratory mucosa. For more information about the CDV Quant RealPCR Test, panels and stand-alone tests, call IDEXX’s team of internal medicine specialists at 1-888-433-9987, option 4, option 2.
