Canine Coronavirus (CCV): Diagnosis & Testing
Canine coronavirus (CCV) is an enteric infection most relevant in puppies or when co-infections are suspected. Quantitative CCV antigen detection supports confirmation of active enteric CCV infection. Point-of-care testing can help identify the pathogen quickly and guide isolation or supportive care.

Clinical Context
Canine coronavirus (CCV) is an enteric infection most relevant in puppies or when co-infections are suspected. Quantitative CCV antigen detection supports confirmation of active enteric CCV infection. Point-of-care testing can help identify the pathogen quickly and guide isolation or supportive care.
Interpretation should combine the quantitative result with the patient's signalment, history, clinical signs, vaccination or treatment history where relevant, and any other laboratory findings. A single value is rarely diagnostic on its own; serial measurements often provide more useful information.

FAQ
How do I choose which canine infectious disease test to run?
Selection is driven by clinical presentation: enteric signs suggest parvovirus or coronavirus; respiratory/neurological signs suggest distemper; travel or regional exposure suggests Leishmania or Toxoplasma. Quantitative panels can run several analytes simultaneously to speed diagnosis.
When should an antigen test be used?
Use an antigen test when an animal is actively ill and you need to identify the causative pathogen quickly. Antigen tests support immediate isolation and treatment decisions.
What are the advantages of quantitative fluorescence testing?
Quantitative fluorescence immunoassay provides objective, instrument-read concentrations with high sensitivity (pg/ml) and precision (CV% <10%), enabling viral-load monitoring and treatment tracking.
What sample is used for quantitative CCV antigen testing?
The quantitative CCV antigen test is performed using rectal swabs.
