How to test the size of a dog: Comprehensive analysis of testing methods and precautions
Parvovirus (CPV) is a high-risk infectious disease that threatens the health of puppies, and rapid and accurate detection is crucial for treatment. The following is a compilation of dog parvovirus detection methods and hot topics that have been hotly discussed on the Internet in the past 10 days, presented in structured data.
1. Common detection methods for parvovirus
| Detection method | Operation steps | Accuracy | Time consuming | Applicable scenarios |
|---|---|---|---|---|
| Test paper test (CPV antigen test) | 1. Collect stool samples 2. After dilution, drop into the reagent plate 3. Wait 10-15 minutes to observe the results | 85%-90% | 15 minutes | Family/Pet Hospital Rapid Screening |
| PCR nucleic acid detection | 1. Submit stool or blood samples for testing 2. Laboratory DNA extraction and amplification | More than 95% | 6-24 hours | Confirmation or early incubation period detection |
| Routine blood tests | 1. Draw venous blood 2. Analyze white blood cell indicators | Indirect judgment (need to combine symptoms) | 30 minutes | Auxiliary diagnosis |
2. Recent hot discussions: Home self-test vs. professional testing
According to the analysis of social media data in the past 10 days, the focus of controversy regarding small-scale testing is as follows:
| Contrast Dimensions | Home self-test paper | Professional laboratory testing |
|---|---|---|
| cost | 20-50 yuan/time | 200-500 yuan/time |
| Risk of false negatives | May be missed in the early stages of onset | Can detect latent viruses |
| Necessity | Suitable for emergency preliminary judgment | Necessary for diagnosis and classification |
3. Detection precautions (key points mentioned frequently throughout the network)
1.Sampling time: The amount of fecal virus is highest 2-3 days after onset of illness, and detection is most accurate at this time
2.Symptom control: The test needs to be combined with typical symptoms such as vomiting, bloody stools, and listlessness.
3.Environmental disinfection: After testing positive, the environment needs to be thoroughly disinfected with sodium hypochlorite
4.vaccine interference: False positives may occur within 7 days after vaccination
4. Latest research data in 2023
| research institute | sample size | Key findings | Release time |
|---|---|---|---|
| China Agricultural University Veterinary Research Institute | 1278 cases | The detection rate of CPV-2c variant strains increased to 43% | 2023-09-05 |
| American AVMA | laboratory data | New fluorescent PCR detection sensitivity reaches 99.2% | 2023-09-12 |
5. Countermeasures after detection
If the test result is positive, you should immediately:
1. Isolate sick dogs to prevent infection
2. Intravenous fluid rehydration to correct dehydration (professional veterinary operation required)
3. Treatment with monoclonal antibodies
4. Unvaccinated contact dogs require emergency vaccination
