1.Which sample is good for use?
In the early stage of infection with canine distemper, it is better to take blood as a sample. At the beginning of infection, there were no conjunctivitis, dry cough, diarrhea and other symptoms, the virus only existed in the blood, if suspected to have canine distemper symptoms, it is more convenient to use conjunctival epithelial cells and urine.
2.What problems should be paid attention to when using plasma testing?
When preparing plasma, if you use a container containing anticoagulant edta, you may interfere with the test results. EDA can also interfere at low concentrations, so avoid the use of edta.
3.What are the limitations of this product?
The reagent is a qualitative screening reagent, which can detect the canine distemper virus very accurately, but if the sample is insufficient or the antigen concentration is lower than the sensitivity of the reagent detection, the negative result may be present, and the doctor shall make a diagnosis result after taking into account all clinical symptoms. An accurate clinical diagnostic result should not be established on a single test result.
4.What is the sensitivity and specificity of this product?
Compared with other similar rapid detection cards, the sensitivity of this card to canine distemper virus antigen was more than 99%, and there was no cross reaction with coronavirus, adenoviruses and parvovirus with similar symptoms.
5.Are there positive reactions when tested after vaccination?
Because canine distemper vaccine is usually attenuated vaccine, the virus increases in the body during immunization and may show positive reaction. However, this phenomenon automatically disappeared after 3-10 days of vaccination. However, animals treated with monoclonal antibodies may be false positive for a long time because they produce secondary antibodies against monoclonal antibodies in vivo.
