FAQ You can easily check the FAQ for answers to any questions you may have.

  • Can whole blood, serum or plasma be specimen for detection?

    Yes, but we recommend you to use anal swap or fresh feces because presence of CPV in blood or serum is limited, and test shows positive only in viremic period. In our instruction for use, blood or serum sample is not included. 

  • How about vaccine virus detection?

    There are several reports that vaccine virus can be detected in the feces by PCR method. So the statement is true that vaccine virus shedding in feces can be occurred. But considering that Anigen rapid Ag test kit is not as much sensitive as PCR method, vaccine interference by rapid test is uncommon case. Plus, there are many commercial CPV vaccines and it is likely to show different vaccine virus shedding competence depending products. In conclusion, vaccine virus detection by Anigen rapid test is not likely, and it depends on the each commercial vaccine.

    Q: For sample  taking of CPV antigen test, the fecal sample should include swabbing of the rectal wall or not? Or just feces from the floor is ok?

    A.It is not necessary to swab the rectal wall. The CPV is propagated in the crypt cells of vili of the small intestine, and is included in the feces. So the virus is mixed in the feces.

  • Is feces specimen collected from puppy’s diarrhea valid or not?

    Usually, a watery diarrhea flushes out the parvovirus in the intestinal tract (rectum). So it can make false negative. So, we recommend you to wait for 30 minutes before collecting the feces swab or to collect feces of the ground or the floor of dog’s cage 

  • Can we use vomit to check CPV Ag?

    The vomit is very strong acid which can give the false positive reaction. 

    Never use vomit to test CPV Antigen.

  • Specimen Collection and Preparation Caution

    1) Sample from canine or feline feces should be used. 

    2) The specimen should be tested immediately after sample collection.

    Q.Pet hospital found the weak positive in CPV/CCV Ag, but negative in CPV Ag. And the dog had no clinical sign. How can I explain this?

    A.Basically, the CPV Ag kit and CPV/CCV Ag kit has same sensitivity. There is no difference. Therefore, this difference could be caused by sampling site, time difference. Also, the test result should be interpreted together with the clinical sign. It can be interpreted a suspected one and then test the dog after 2 days later or testing CPV Ab test kit is recommended. 

  • I want to know parvovirus shedding period in feces.

    CPV is transmitted by oronasal exposure to virus-contaminated vomitus, feces, and environmental fomites. The virus can also be spread by rodents, birds, and insects. The incubation period ranges from 3 to 14 days but is typically 5 to 7 days. Virus shedding in feces begins 3 to 4 days after exposure during the preclinical incubation period and continues intermittently for up to 2 weeks. Dogs with subclinical infection also shed virus in feces. Thus, infected dogs may be contagious for up to 30 days after exposure
