Molecular Diagnostics

Clinical Testing
We offer tests for a wide variety of infectious disease agents and several genetic assays. For questions regarding routine veterinary molecular diagnostic clinical testing, please contact our lab manager John Beeby (jsb76@cornell.edu or 607-253-3679).

Starting April 5th, 2017, results for most routine clinical testing will be provided in the following format (please see our Johne’s testing page for specific interpretations for the Johne’s direct fecal PCR):

  • Not detected
  • Low positive
    Previously called “suspect,” this indicates that the pathogen was detected but at a level that was so low that it may not be reproducible.
  • Moderate positive
  • High positive
  • Inconclusive
    This indicates that the presence or absence of the pathogen could not be determined due to inhibitors present in the sample.


These interpretations are based on the Ct value obtained by tests performed using real-time PCR. We no longer provide the raw Ct values routinely due to the differing ranges produced by our platforms and have replaced this with the interpretations above. If you would like to know the Ct value for a clinical specimen, please contact us.

Research Support
As an academic lab, we are eager to form collaborations with other researchers and provide support for a wide variety of projects. Dr. Laura Goodman is our lead faculty for research and development. Please contact her or section Director Dr. Amy Glaser to discuss research collaborations.

Several recent publications highlighting work that we have contributed to include:

  • Wagner et al. Neonatal Immunization with a Single IL-4/Antigen Dose Induces Increased Antibody Responses after Challenge Infection with Equine Herpesvirus Type 1 (EHV-1) at Weanling Age. PLoS One 2017
  • Khatibzadeh et al. West Nile virus-specific immunoglobulin isotype responses in vaccinated and infected horses. Am J Vet Res. 2015
  • Levy et al. Prevalence of infectious diseases in cats and dogs rescued following Hurricane Katrina. J Am Vet Med Assoc. 2011


Discounts for high-volume research testing may be offered, and we are happy to provide raw data in spreadsheet format including additional standards, copy number interpolations, and/or replicates if needed. These samples must be submitted in batches, and fecal samples should be pre-weighed into 400mg aliquots in snap-cap microcentrifuge tubes. Please contact us to discuss the specific needs for your project.

We are now pleased to offer whole genome sequencing of bacterial isolates for research and surveillance purposes. Please contact Dr. Goodman if you have a need for this service, for which we are currently charging $50.

Surveillance Testing
As a level I NAHLN lab, we perform surveillance testing for avian influenza virus, avian paramyxovirus-1/Exotic Newcastle Disease, foot and mouth disease virus and classical swine fever virus. We also participate in the FDA Vet-LIRN and GenomeTrakr networks to improve pet food safety and outbreak response capacity.

In cooperation with our Bacteriology section, we perform Johne’s direct fecal PCR testing for the New York State Cattle Health Assurance Program (NYSCHAP) and Salmonella Environmental Surveillance for equine facilities.

Assay Development
Development of new assays to meet emerging needs is part of our mission, and we welcome feedback from our clients. Please get in touch with us to let us know how we can help you meet your molecular testing needs. Our current priority areas include:

  • Tick-borne disease testing
  • Next-generation sequencing based pathogen discovery
  • Multispecies enteric panel development
  • Bovine respiratory pathogens
  • Feline respiratory pathogens
  • Wildlife testing
