The initial diagnosis can be made based on the mental state of the puppy and whether there are symptoms such as vomiting and diarrhea. For example, canine parvovirus can be diagnosed based on symptoms such as vomiting, bloody stools, dehydration, and fever. In addition to testing based on clinical symptoms, there are many more commonly used testing methods:
1. CPV rapid test kit. Based on colloidal gold immune technology, CPV rapid test kit is easy to operate, and pet owners can self-test at home. It can detect CPV antigens in dog feces, and the results are generally available within 5 to 10 minutes.
2. Enzyme-linked immunosorbent assay (ELISA). Based on the antigen-antibody reaction, veterinarians can usually complete a CPV stool ELISA test within 15 minutes to detect CPV antigens in dog stool.
3. Polymerase chain reaction (PCR). The PCR test can detect small fragments of viral DNA in the stool of infected dogs. This test is more accurate than both rapid test kits and ELISA, but the PCR test requires higher technology and equipment.
4. Virus isolation. Viruses can be isolated and identified from CPV-induced myocarditis and enteritis.
